Wireless Connection Slow And Unstable
May 31, 2011
I recently moved back home with my desktop that use to be plugged in via ethernet. I bought a PCI Wireless card and I have been having problems connecting to and staying connected with the network. Once I am connected the connection speed is very slow. I have tried reinstalling windows and my card several times, even going to the store to swap it out. I have a feeling that one simple setting is changed, but I can't figure out what it is. I am currently on a laptop that is also running windows 7, but has none of the problems of the desktop. I tried to run the Netalyzer program on the desktop, however, the network disconnected as soon as I tried. Here is the link to the results from my laptop that is connected to the network: ICSI Netalyzr — Results

I've been having big problems with my Belkin router. The connection is often slow even after restarts etc. I'm not sure whether it's the line quality/broadband usage/router quality that's causing the problem. How can I pinpoint the issue?ISP: Virgin MediaBroadband: ADSLAnti-Virus: AVGI've attached the image and ipconfig text file.

So my issue has been going on for a while now a while after I replaced the router from a DIR-535(If I recall) to a DIR-635. Now the problem resides in my computer however as it would seem that I randomly tend to loose internet acces and it only applies to my computer in the form of obviously loss of internet and the horrid warning triangel in the corner. I've tried removing and restarting the connection without any succes, I also tried to do a ipconfig /release /flushdns and /renew but it didnt seem to do anything either, basically been throwing attempts at a wall to see what works.
As far as the actual card goes it's a Atheros AR9285 Wireless Network Adapter.

I have a Linksys WRT110 wireless router for my desktop via a D-link DWA-125 wireless adapter. The OS is Windows 7 64 bit and I mainly go online to play games. This has been a while and every time I play games, which requires stable connection, I will get this lag (the ping goes as high as 600ms for every few seconds then goes back to normal).I tried many ways to troubleshoot and find no solutions. I updated firmware for USB adapter, power cycling the router and reset the router many times.

I bought the WMP600N because Linksys and Microsoft listed it as 'compatible' for Windows 7 x64. My experience:
- unstable and weak connection
- pings to websites like google.com drops, average: 1 out of 3
- low signal, on the same spot my three years old HP-laptop with 'a build in wireless card' has full signal strength in Windows 7
- it works well under Windows XP (32 bit)
I am convinced that drivers for the WMP600N are not ready for Window 7 x64. Linksys (or Ralink, which developed the chipset), release a proper driver for the WMP600N.

I have had my EA2700 for about 6 months now. Have had no problems until about a month ago. One night I could not get the router to connect to the internet. First thoughts were that the cable connection had gone down. When I finally started to trouble shoot I was able to confirm the cable connection is fine by connecting to the modem directly.
Out of the modem I am getting 14+ Mbps. (I only Pay for 10 So a plus there)
I could not get the router to connect to the internet. I ended up resetting the router and reconfiguring it. Ever since then I have been getting really unstable connection to the internet.
When I connect directly to the modem (cabled) I am getting a nice steady connection . When I add the router and hardware in I get a good connection only a Mbps or 2 drop off and a pretty steady connection. Then when I connect over WIFI I get a much larger drop off depending on if the device is a 2.4 or a 5
The connection is extremely unstable. The curve on the graph {URL} is very peaky and has extreme highs and lows. This is multiplied when running on the GHz (as my laptop runs on). My Iphone running on GHz. I can pull down 9 Mbps but the curve is still up and down. Iphone on GHz I barely get Mbps and it is extremely choppy on the graph.
I am able to back this up with my I PAD. I can only confirm the 2.4 number with the laptop as it does not have GHz radio in it. So every thing that us running on the 2.4 is getting poor connections.
I also suspect that the through put on the wired side is poor as well. I am unable to prove it as every test I run shows a good connection but netflix has been locking up and I have to restart what ever I am watching 2 to even 10 times a show. I need to do more testing to be sure the network or the devices are to blame.

Just installed a refurb EA4500 this past weekend after testing it for a week. The regular wireless network is very stable, but not much faster than my single-band DLink DIR655. Guest network seems to drop out from two connected iPhones, and when the connection drops, you have to re-login and type in the guest password everytime. The linksys firmware is up-to-date( Linksys smart wifi)and so are the iOS on the 2 iPhones. Just to add, on my old DLink, the guest network comes up secured also, so when you type in the passcode, it remembers it next it comes in range unlike the Cisco, which requires login at a web interface.

I have a Motorola Surfboard cable modem with a Comcast account that is supposed to get "up to 15 mps". My desktop works gloriously, but my laptops and everything else hooked up to the net through my Media link Wireless N Router either run incredibly slow, or get kicked off completely.I've already had the router replaced one.

Model : TL-WDR4900
Hardware Version : V1
Firmware Version : 3.14.3 Build 130320 Rel.39025n
ISP : PCCW Netvigator
I have upgraded to the latest firmware which solved lots of problems regarding unstable wifi connection as well as BitTorrent / P2P transfers.But I also observed that when my BT is on (Transmission for Mac) at around 50KB/s upload and download, my network latency hikes up from some 30ms to 500ms which affects a lot on web browsing or other apps requiring Internet.My BitTorrent app is showing I am merely making some 20 peers connection so I am not convinced that is an ISP problem but it's more about the router.

I have recently built a new computer and now I am having trouble with my network connection. When I was done I directly connected it to my 2wire modem with the Ethernet cable.There was no connection until I downloaded the LAN driver from the CD that came with the motherboard [ASUS M5A88-V EVO ATX]. It worked for a few days and then the connection just started dropping. The trouble shoot in Windows 7 fixed it - but only for a while until it didn't work at all. Restarting the computer restored the connection and usually gave me about a few hours to work with, but a few days later all I had were a few minutes. Other than this computer I have two laptops [Windows 7] and a desktop [Windows XP] which the internet runs smoothly on when hardwired to the modem and I didn't have to install anything. Some messages I get from the trouble shoot are:LAC doesn't have valid IP configuration Default gateway not available Unidentified network?

My laptop has a very unstable connection and I am completely stumped. I've monitored the ping and it is usually around 32-50, but it constantly spikes to 3k+ for roughly 10 seconds, it also disconnects at random intervals. I've tried updating the networking drivers, disabling firewalls and changes the preferences.
I have a Samsung Series 7 Chronos running Windows 7.

Since a few days I've installed my Sitecom 300N Repeater to extend the wifi signal at my home.I named my repeater the same as my wifi UPC modem (Cisco EPC3925), so the PC will see 1 connection instead of 2. I also turned off the DHCP server on the repeater (not sure what it does, but it was recommended when I was goggling around).fortunately I'm experiencing a lot of trouble. Although I can connect to the repeater, the signal is not always stable. Many times my connection speed is as low as 3 Mbps. When I quickly turn the power off and on it instantly jumps back to around 40 Mbps and stays like that for a few hours/days.It's very hard to debug this problem because after resetting the the repeater is doing very good until it slows down or even dispersers after a few hours.

I don't know if this because buggy firmware (i updated to V1.00.16) or there something wrong with the device but if i set radio band to AUTO which enable wide-channel, my wireless connection become unstable when i ping to the modem, i got 200ms - timeout randomly
my family notebook that on other side of room connection also become more worst , ping to the modem (192.168.1.1) timeout so often
the connections seems better if i set radio band to standard - 20Mhz channel even though it seems WAG54G2 have more stable wireless connection (i replace it because the ethernet port dead) i also tried to change the channel, but the issue still persist, it seems the default is the most stable (channel 9 for wide, 11 for standard)
should i RMA the product as i just purchase last week? or it just because the bad firmware ?

I've had two 932Ls for a year and they work fine. Both installed trouble-free and have been used with motion-detection wirelessly. I often go straight to their local IPs in my browser to make any changes to settings etc (avoiding myDlink). I just bought two 930Ls (don't need/want the IR-function on these) and tried to install them. Process went seemingly smooth but once the camera was installed and wireless, problems started to crop up. As I saved settings in the web interface, I would get 404 "page not found" errors. Refreshing would make it work again...sometimes. More often than not, I cannot reach it through the web interface and the camera reads "disconnected" in D-ViewCam. It usually works on myDlink though. i've checked all the network and wireless settings and they are identical to my 932Ls. The connection is just unstable for some reason. The problems are apparent in the web interface and D-ViewCam which also means I can't trust the motion detection and emailing function. It is also NOT visible in my Windows 7 network environment, whereas the two 932Ls (and my entire Sonos network) do show up there.The 930L is running firmware 1.04 and the 932Ls are running 1.02. I know there is a 1.06 available but before I try that I'd like to get your views on this problem. Could it be a faulty unit? I don't want to fight through this problems - if it persists I'd rather return the cameras and buy two more expensive 932Ls and just turn off the IR in the interface. Or is this a known issue with the 1.04 firmware?
Even writing this right now, the camera suddenly popped back up on the web interface inexplicably, without me doing anything. and back up on D-View Main Console.

I am currently seeing some stability problems with a 2504 WLC and a wireless bridge (Netgear WNCE2001 to be exact). The wireless bridge can connect to the network, but is very unstable. It will disconnect after 5 - 60 minutes of operation.
I believe part of the issue is that the bridges, when associated, do not show up as a WGB according to the WLC.
Any WGBs that are known to work well in a controller based environment? The WLC is running 7.0.220.0 and the APs are 1142s and 3502s.

Before I put in place any network security appliance POC, my wireless network worked fine.Note: ethernet works fine all the time and confirm my internet is okay too. Just wireless.
First time, I got Palo Alto vendor to setup POC. It screwed up my wireless. We removed on 1st day itself and re-configured everything all over again.Now before holiday break, Sonicwall vendor setup POC for us. It worked fine though for 1 week and now the wireless gone crazy again.
3 bars, 2 bars, 5 bars, sometimes no bar.Then when there's POC, my guest wireless network will dead too.
I can't figure out the problem and what's causing such instability?If I understand correctly, this is how my network works:-
sonicwall nsa 2400 (router 192.168.1.1)
cisco linksys wireless (before sonicwall, we used this as router. Now used as wireless access point).
tp-link 48-Port 10/100Mbps + 4-Port Gigabit Web Smart Switch
is there anything in particular I should take note about? or any tools to analyze my wireless network problems?

I bought a Netgear N600 wireless adapter (WNDA3100).I used wired before mostly without problems but was annoyed by the cables.My router is a Netgear WNDR3300 and I never had problems with it.The problem is that sometimes my wireless adapter just stops working and drops the connection.I use it since a few days, and it already happened several times.It happened especially when I was streaming videos to my PS3 (my PS3 is also wireless). It also happened while I was watching Youtube videos. When this happens, I need to unplug the adapter and plug it again. Sometimes, I need to restart the whole computer for my adapter to work again.Is this normal with USB wireless adapters? This is unacceptable to me.I want a stable connection.

I recently found that whilst using my WIRED connections, web pages have been opening slower at times. My ping times to google.com usually is around 72-84 ms which I continue to get if I hook up the cable modem directly to the PC. As soon as I utilize the Linksys router, I start getting higher ping times anywhere from 72-300 ms. Firmware version is 1.5.01 which I recently upgraded to. I tried resetting and so on. Is there an older firmware version that works better? I'm currently running Windows 7 Ultimate 64-bit.

Region : Netherlands
Model : TL-WDR4900
Hardware Version : V1
Firmware Version : 121211
ISP :
after changing from a Thomson router with wifi to the TP-link WDR-4900 I find that the wifi is very unstable. The 2.4GHz is operating on the same channel as my previous router (channel 8 - which is the lest busy channel around my house), and none of my neighbours have wifi on the 5GHz band. Almost all devices in my home regularly have to reconnect to the wifi, both on the 2.4GHz as on the 5GHz (tested with more than 8 devices). Almost every 15 minutes I see a "wifi channel disconnected" message, 10 seconds later followed by a "wifi connected" message. the Wifianalyser app on my tablet confirms that the wifi signal drops once in a while to zero. I use the latest stable frmware (I read that there is beta firmware but I don't like to loose warranty). The stability seems to unrelated to the amount of traffic on the wifi network.
Will this be fixed in the next firmware of the TP-WDR-4900 ?

If I send video file(overall bit rate is 17.5Mbps) to client with 2.4Ghz band, it always freezes and go repeatedly around 1 second interval. the distance around 10m away without any wall, open space actually.
But same condition with above, cheaper wireless router no problem at all. It happens only with EA4500. And there are no any parameters setting menu actually.

I recently replaced my old WRT54G router with a E3200 router.
Unfortunately, ever since my wireless network is a lot more unstable than before. I very often experience serious lag spikes and drops in speed. Very often I experience serious lag for a couple of seconds after which everything returns to normal. I notice this the most in online gaming, but it is also noticeable while browsing the web. When downloading large files (e.g. steam games), the download speed also seems to suffer from this by dropping every now and then.
There are no connection drops however. And it only seems to affect the wireless network.
I have configured the E3200 router manually using the Web UI and is has been configured exactly the same as my WRT54G: i.e. only 2.4GHz band enabled with b/g/n, WPA2 security, MAC filtering on, no throtling/parental control/port forwarding, UPnP disabled. The E3200 is in the exact same place as the the WRT54G was.
Things I have done so far for troubleshooting: I used inSSIDer to monitor the wireless network and it's signal strength seems about the same as the WRT54G. I changed channels for best signal strength (there is only one other wifi network that seems to be configured as a dual channel N network; 3 other networks with very low signal strength) and have tried every channel.
I updated the fimware to the latest version (Ver.1.0.04 (Build 1)) and did a factory reset and power cycle afterwards.
I noticed that switching channels can account for 5-10Mbps differences in internet speed. Something I never noticed with the WRT54G. The lag spikes occur more often on some channels than on others. This seems not related to the speeds I get on the channel.
I really can't imagine that a router marketed as High Peformance router with superior speed and superior range is less stable than my old WRT54G router.
Is there something I can do to improve stability of this router?

I am using a Samsung N210 with 2GB of memory in it and Windows 7 Starter. When I use the wireless connection the "Connection Status" shows as 72Mbps, which is to be expected considering I am only a few feet from the router.the speed is nothing like that in reality. I tested the actual transfer speeds for the wired and wireless connections by copying a 238MB folder with 77 photos in it. I copied it from the NAS device, where I store all my files, to the local disk of the netbook.

I subscribe to Comcast internet service, at 10 mb/s. When connected wirelessly on my HP laptop, my internet is painfully slow, around 490 kb/s. However on my other laptop (a Sony VAIO) the internet speeds (wireless as well) are fine. Also, when I connect the HP by ethernet, the internet motors along at full speed. My specs are below[CODE]

i have a 4Mbps DSL internet connection with 3 PCs connected through a router. 2 are connected wirelessly and the other is wired via an ethernet cable.i noticed that when downloading a file from an international server, the transfer rate on the wireless PCs is 2-3 times slower than on the wired PC. the wireless PC would get about 150-200kb/s, whereas the wired PC can max out to 450kb/s on a single download.however when i download from a local or nearby server instead, the transfer rate on the wireless and wired PCs are the same and can both reach up to 450kb/s per download.i don't understand why the wireless connection is slower to international servers compared to the wired PC. don't they all go through the same router? or am i missing something?my wireless signal is at 54Mbps with "excellent" strength. i also tested the ping results from both the wireless and wired PCs to international servers and they are pretty much the same. there doesn't seem to be any extra latency all PCs are running windows XP SP3- the modem/router is a D-Link 2640B

I just had comcast internet installed, and am using a linksys wireless router (WRT160N). When I connect my netbook to the network it gets 0.7mbps on speedtest.net, when I use my girlfriends laptop it gets 16+mbps. I have tried everything, I am at my whits end. I have updated my firmware, updated windows to the the limit and reset the settings on my router. If I connect my netbook directly to the router I get 20+ but wireless is 0.7 and upload speed stays the same. I am using an HP Mini 210-2000 with windows 7 starter, I have updated it to service pack 1 and have all the windows based drivers installed. I have not tested it on another wireless network to see if it gets the same terrible connection. I don't know if its something with my computer, windows 7 starter, or the way my computer talks to the router

So, first of all, I have two PCs in my home, one connected directly to the router, the other connected through the wireless network. I use the wireless connected PC. In the past I've had some issues of my connection cutting out on random occasions for about a minute then reconnecting back. This happened to every single user connected to the network, including the one connected directly to the router. It was just a minor nuisance so I just put up with it. However, one day my internet just slowed down to a crawl and I don't think any hardware/software changes were made to cause this, but I may be wrong. What confuses me is that, now the internet has slowed down, the disconnecting issue is a very rare occurrence. It happens probably once a day, where as before it was much more frequent. I assume it has something to do with my network not being so strained. The PC connected directly to the router does not seem to have this issue, in the speed test below, it has a higher download rate, around 6-7mbps I think (it's pretty bad in this area, but it's usable).I have done some research as to why this is happening, but there are so many different diagnoses for a slow internet that finding the one I'm having is really difficult. I thought it was just my ISP performing maintenance but it's lasted for about 4-5 days now.

My daughter tells me that the "internet is soooo slooowww" on her laptop with our wireless network. So I go to a couple of speed test sites on her computer and sure enough the speed is abysmal. So I pull out my laptop and the speed is great. So we know its her computer that has the problem.

I have an NTFS formatted USB disk drive (Western Digital My Passport Essential Black 320 GB WDBAAA3200ABK) attached to the WRT160NL wireless router (Firmware Version 1.0.02), and I have video, picture and music files on the USB disk drive in three folders: Videos, Music, Pictures. Auto-scan is disabled, I scan the media files manually by clicking on the 'Scan All' button.
PROBLEM 1 The worst problem is that the router is very sensitive to files that can't be recognized by the router as media files. For example if there are subtitle files (*.str) between the media files, then strange and nondeterministic things happen: some valid media files are skipped and not included in the media database; some files included but the file names are mixed. The most irritating in the bug is that there is no log file, where you could find the problem, and so you never know which file cause the problem, and you have to browse through all the files hunting for the cause.
PROBLEM 2 When the router is in the process of scanning the media files, then the internet (WAN) connection often can't be used, although the router can be accessed and the status says it is connected to the internet.

i have a little annoying problem with my E4200. V1 with the latest 04 fw. It seems, that after many hours of downloading at full speed (only one torrent at a time) the speed goes down, and up again, and becoming unstable. My max download speed is 1.5 Mb/s, and it can drop from that, to 50 kb/s, and then up again. and i have no internet access when that happens, but it only last 10-20 seconds and then its back again. Sometimes i get that yellow warning sign on the taskbar which says "No Internet Access" but not always.
Seems like its happening after many hours of downloading at full speed. im on the latest firmware, have tried different channels, 20 Mhz only on Channel Width, different names on the 2.4Ghz and 5Ghz channels.. i use the 2.4Ghz channel btw. Otherwise its stable, and i have had no problems while gaming online.

I recently moved to a new apartment to be closer to work and this apartment complex is only covered by what I was told is a wireless hotspot.Basically, a wireless devices connects to the SSID, logs in, and then you're set with the most pitiful internet still available.Now I was told I could pay $70 bucks to have these people (Onlyinternet.net by the way) install a device that would allow me to connect my desktop to the internet service. Wasn't thrilled about that. Its $40 a month, for a 1Mb connection so that wasn't going to happen anyway.Looked up internet connection sharing and had setup my laptop to use it with my desktop.My connection on my laptop has always had a very low signal; between one and two bars no matter where I'm at in my apartment. If I go outside it'll get about 4 bars but that is about it. The actual speeds listed on the Wireless Network Connection Status go from 1Mbps, 2Mpbs, 5.5Mpbs and 11Mbps. Never higher.Today I went and picked up a NETGEAR N300 wireless router. My hope was that the router might be able to pick up the wireless connection and I could just connect through my router instead of having to use my laptop. Apparently, this is not the case.I have to use my laptop act as a modem and have it plugged into the Internet port of the router and then my desktop connected to one of the LAN ports on the router. Is this setup better then using the internet connection sharing deal? Is there any other way of increasing my signal strength and network speeds?
