Lot Of Drop-outs / Random Disconnections And Slow Speed?
Sep 25, 2012
I have setup the existing wifi router (couple of years ago) so do have the basic networking knowledge but am not up-to-speed with all the latest developments in the industry2. ISP have provided a '******' ADSL modem that i need to connect to get this whole netwrok working. its only supports ethernet connections - (i live in a third world country)3. I have installed a TP-link Wifi router (WR841Nd). The modem on stand-alone basis is fairly decent, covers decent range on ground floor (my house is fairly big and is double story building) but with few dead spots. It supports N series so speed is quite good as long as one is within range.
Problemi have been living with it for couple of years but since recently i have been experiencing a lot of drop-outs/random disconnections and slow speed. I have tested my wifi router at friend's place and it showed no signs of problems so it has to be my ADSL modem (phone line is fine, though i am not close to exchange but that is not an issues as my neighbours are using the same phone line/ISP and they dont have an issue)another problem i have is the coverage, my current wifi only covers the ground floor and i would like to extend this to upper portione am looking to change my ISP provided ADSL modem. The problem is i dont know if i buy an ADSL modem off amazon and whether it would work or not because the setup is not straight forward and the ISP staff is corrupt. They dont provide with quality hardware neither do they have technical competence so i literally have to beg them at time to at least come and see the problem.Question1: ISP provided ADSL modem replacementi know the settings for ISP modem so i can search how i can replicate the same with Billion but can this work?Question2: RAnge ExtenderI am thinking of buying couple of powerline wireless extenders from netgear.

I have a Lenovo T420 with a Intel Centrino Advanced-N 6205 wireless network card that causes me some headache. It randomly gets disconnected from my router (Zyxel P-2601HN-F1) and home network, works fine though if i using cable. Right after it gets disconnected it reconnects and works fine until it gets disconnected again. I have an HP laptop connected at the same time and no problems there.It works fine in the network in our office (work laptop). I tried our IT dept but they were clueless and told me I had to figure it out by myself, as it works in the office..

This is not a problem I would not have noticed save for starting to use Skype. Every 10 to 20 minutes, my internet drops out. This occurs whether my laptop is connected via LAN cable or wirelessly to the router. Skype drops down to one bar, then drops out, and tries repeatedly to redial, sometimes achieving a very scratchy voice call for several seconds before dropping out again. If you redial in 2 minutes, it is fine and achieves medium quality video calls. Whilst skype is floundering around, I can sometimes browse the internet, but sometimes it is offline. I have phoned my ISP and they claim no problems on their end. Beyond that I really don't know where to start on looking for the problem.

Ok, I have a huge problem with my wireless connection. It will constantly lose connection to the internet from my PC, IPod, Laptop etc. What will happen is a yellow warning triangle appears which tells me I've lost internet access. I have had the modem checked and replaced by the ISP with no success so it's likely that it's not a problem on their end. I've changed the wireless channel to move it away from my neighbours with no success.
Here is a copy of my ipconfig /all when the connection dropped out:
C:UsersKevin>ipconfig /all

We sort of recently got wireless internet, have had it for 2-3 months now I think and everything was running smoothly. Yesterday my internet randomly disconnected and it was only from this (my) pc, the internet was fine for everything else in the house which includes another pc, 3 laptops, cellphones, ipods, and gaming systems. It has been going out randomly since maybe 6pm yesterday. I have to completely restart my computer for it to work again. The only thing I tried was to unplug the modem and router for a bit and plug them back in, which did nothing for my computer lol. When I did that though the other computer had an ip conflict that came up which it's had in the past with my own pc but after I restarted my computer they were both fine. My computer still has random disconnections from the internet though. I don't understand why my computer is the only one affected and why it's starting now when it's been fine for the 2-3 months it's been working.

this had happened for a few months and i did not really mind until the disconnections worsen. usually when i power on the router and started using the internet, it will disconnect randomly once. my wireless SSID will disappear and lost connection. and no matter how i refresh the SSID still won't broadcast.
the only way to get back internet access is to re-power on the router, so the SSID will be broadcasted again.
my wrt54g2 V1 router had recently upgrade to the latest firmware version,1.0.04. but still disconnects as usual. however the disconnections only happens once, after u re-power on the router, you will not disconnect again.
but after turning off my laptop, and use it again after few hours, the same thing will happen again, a random disconnection and got to re-power on the router.

I have installed 4 of these units in a commercial premises offering free wifi. Since the day they were installed (5Months ago) we had connectivity issues with mobile devices. This was somewhat resolved in the latest FW 1.0.04 but we are still having random disconnections on the units every 2 - 4 days and have to reboot the units. Lately the units have become unresponsive and reset themselves back to factory settings.
What we have done so far:
Changed router models - No change
Changed from Static IPs & DHCP - No change
Turned on isolation - No change
Performed a wifi analysis to pick the best channel for each unit - Slight signal gain but still disconnects
Changed to 20Mhz only (And all other variations) - No change
I think I am left with no option but to return these for some other brand. I'm really regretting buying these units at the minute...

We have a Cisco 4400 WLC running version 7.0.220.0 and are experiencing clients randomly dropping both broadcast and multicast at the same time. This is not specific to one area of the site and the duration of the MC/Brodacast loss varies. These comms outages don’t happen on all the clients at once but usually affect one client at a time. After a few minutes or a few hours, the client will start receiving the multicast without user intervention.
The site has Cisco 1522 AP's that have rather interesting logs where the DTLS sends fatal errors, followed by CAPWAP going into discovery state. Not sure if this has the same affect or if that's a completely seperate issue.I was told it could be the GTK but I don't believe 7.0.220 has this feature even enabled. The clients are Cisco 3230 and Cisco 1310's. The clients are running version 12.4(25d)JA1 while the 3230 router is running version 12.4(24)T7. What supporting logs or configs need to be shared to better troubleshoot. This has been going on for quite some time and is frustrating the end user as multicast is essential to the operation.

Ok so I have a Netgear dg834gb v2 and I have a disconnecting problem on a wireless connection for my laptop. When I am using my laptop, my connection will drop at random moments mostly when I'm playing League of Legends. If I'm not playing it rarely disconnects. It drops for about 10 seconds and comes back up usually, but sometimes I have to reset the router. It only recently started happening and I have no idea why. Maybe it can't handle when I'm playing?

I have used DIR-655 (HW:B1 FIRM: 2.00NA) with Motorola SB6120 for sometime without any incidents. My dl speed usually is around 26mbps. Lately, it happens twice that the dl speed drop to 10mbps. If I connect the SB6120 directly to my PC, the dl speed is 30mbps. Is my DIR-655 dead?

I recently upgraded to 1.0.3 fw on my x3000 in the hope of getting rid of the issue with my upload speed. However, now it is denying me connection to the outside world about once a day. It is getting an ip, even if I am renewing the IP address.I am using it on my Fullrate broadband 20/2 connection, and I can at most get 1mbit UL, but with the old router, I could get 2.1mbit. I bought this one because the other one sucked (the standard from my ISP).I have set the router up as the old one was, however, it is still slow, and now it also needs reset every day.

Where I try to download files and they do not download. They only download for a few seconds before not receiving any internet connection. Then after a few minutes they slowly download at only a few KB/s before completely not downloading. I also notice random slowdowns when browsing the internet or whatever I'm doing that uses the internet.

I'm pretty new to networking. Purchased a E4200 for my home line. When i connect directly through the modem i see speeds of about 600mbps but when i connect through the router via an ethernet cable on an empty port on the back of my e4200 my speeds drop to about 180mbps. I expected a speed loss going through wireless but why i am experiencing a speed loss by using the ethernet as a passthrough? I thought the ethernet ports on the e4200 were gigabit and support up to 1000mbps?

I purchased a WRT110 router about a 18 months ago. I am currently experiencing an issue where the wireless connection to the router will become randomly erratic. My internet connection will slow down or drop entirely. Sometimes my laptop will disconnect from the router entirely. I don't think it's the wireless card in my laptop since I have seen the issue on my desktop using a wireless N USB adapter, my Nintendo Wii, and my wife's Macbook, all within the last week.
I am positive it is the router. I set up a coninuous ping command to the router accross my laptop's wireless using "ping -t 192.168.2.1" in a command prompt. Most of the time, the round trip is 1 to 3 ms or <1 ms. When I am experiencing the connection issues, the ping time will rise significantly, sometimes going as high as 2000 - 3000 ms. About 25% of time, the ping will just time out. When this starts happening, the only way I have been able to restore proper connectivity is to manually reboot the router. The issue eventually re-appears. Sometimes in a few days, sometimes in as little as five minutes. I've gone so far as to restore the router to factory defaults and reconfigure it, but that has not made a difference.

Recently my desktop has experienced very slow download speeds (~0.11 Mbps), however the upload speed appears to be in line (~2.0Mbps). These numbers are taken from Comcast's speed test (my ISP). It is obviously a problem with my PC because everything else on the network (PS3, Laptop) have great signals with no problems. I just recently reverted the Desktop back to its factory state, and everything was working fine for a couple of months. The desktop in question uses Vista 32-bit and the Belkin Basic USB Wireless Adapter.

I live in the tampa bay area, I have bright house (BHN) as my service provider, which provides a Road Runner Lightning (40/5) package. I previously used BHN's top tier (20/2) back in July (and prior) with no problems.
After converting to Lightning in August of this year (2010). Of course, BHN (and every other provider) wants to force a modem/router down your throat, so I had them bridge it (in short, turn it into a dummy modem with no routing). I had an SMC branded modem gateway at the time. I work from home 2 days a week (so I can spend more time with my kids during morning, lunch, right after work) and this requires me to use QoS to ensure my VOIP work calls don't get dropped, if the family is watching youtube videos or watching netflex.
My network was as follows SMC Modem >WAN IP>>WAN Port>>D-link DIR-655>>Switch Ports>PC1, PC2, PC3
Everything seemed fine (from a usability stand point) till about 2 weeks ago when my upload speed seemed to grind to halt. Normally I was able to upload about 200-300K per second, and I noticed this dropped to about 45K per second during a drop box upload. First thing I did was power cycle both my modem and router (in the proper/usual order). After they both come up, I start using speed test to find out what my upload speeds were. I was getting about 39Mbps down, but only .56Mbps up still. I factory reset my router.... test, similar speeds. Power cycle all computers (just in case), and then modem/router. Tested, similar speeds. Updated the firmware to the latest. Same issue
Called BHN customer service, they factor reset it, but it wasn't in bridge mode. If I by passed the 655, in factory mode (non bridge mode) upload speeds returned to better than expected states. If I bridged the cable modem, upload speeds seemed to crash.
Had BHN replace the modem, seemed fixed for a day, then issue came back. Had them come back out and replace it again, this time with a Motorolla Surfboard modem... same issue. Fine during factory reset, however after they bridge the modem, upload speeds were fine. Told BHN I would take it from there.. Connected up the DIR-655, and upload speeds crashed again. (.6Mbps). Called D-Link Support, and the Chinese English speaking rep seemed to not be listening to me and tried to have me adjust my MTU as well as Wireless settings. Long story short... the rep was a level 0 id10t and I hope D-link will consider hiring better employees/contractors. So I was all about to give up and replace it with a DD-WRT capable router (which it takes me a lot to want to swap hardware), when I discovered the wan shaping was on. Which I thought to myself... nah... QoS has never messed up before... why would it be the cause. Turned off wan shapping... and voila. Issue seemed to be insta-resolved.
Unsatisfied with that... I decided to dig a lil deeper. I turned on Wan shaping again, but decided to set the settings manually instead of auto detect.
Here are the settings I used... (Advanced Tab>QoS)
Enable Traffic Shaping - Checked
Automatic Uplink Speed - Unchecked
Manual Uplink Speed - 5000
Connection Type: Cable or Other Broadand Network
Enable QoS Engine - Checked Automatic Classification - unchecked (this checked seemed to affect my upload speed by about 5-10% during testing) Dynamic Fragmentation - unchecked (this checked seemed to be the worse enemy for upload speed)
While I know I'm not any network guru (still have to use a subnet calculator for subnetting), I think I did a pretty good job drilling down the issue (once I got passed my service provider replacing modems).
Anyways, I've had overall good luck with D-Link products, even have a 5 port 10/100 switch (all metal) from 1998 that works great. Hopefully, D-Link will just either put more documentation on the web, or hire better employees.

isp is Comcast. They have had 2 techs come out here to look at problem and found nothing. I'm on a wireless connection with router in the next room. Modem was replaced a week ago and still problem persists. Landlady says she has no problem (shes the one in the next room and is connected directly) but I think that because she doesn't notice (I play online games so its very noticeable). I have excellent signal from router. This is my report:

I'm having problems connecting to the Internet using the wireless adaptor - it will connect initially but the connection is very very slow and then will eventually drop out and stop working.When I connect using an Ethernet cable, there are no problems whatsoever so I know it is not a service provider issue.I have updated the BIOS to A11 and all drivers are up to date. The wireless adaptor is Intel Centrino Wireless-N 1030. [code]

I've been having this problem for quite some time, mostly since my mother bought her first Asus Laptop that came with an Asus WL-530g V2 wireless router.Problem is sometimes I get a random disconnect where Local Area Connection is identifying. On some occasions it reconnects on it's own after a few seconds, other times I have to diagnose the problem and I get a "Windows doesn't have a valid IP config" problem but it fixes that.The other problem, and I don't know if the two are related is that very often, for short/long periods of time I get a drastic reduction of internet speed. From what I can tell, it's got to be something to do with the network configuration or the actual router itself, it's very old and Asus stopped making firmware for it in '09. Useful data Basically I have a wired connection from my desktop to the wireless router.

Network running about 60 computers, most of which are running windows 7 professional. Some are on a domain, some are not.At (seemingly) random times, some computer on the network will lose the ability to browse websites (including the web interfaces of networked devices). I can't identify what circumstances cause this to occur. I only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.

I purchased an Advent DT2410 about a month ago from PC world. It came with Windows 8 OS a USB wireless stick and the following basic spec:
Intel® Core™ i5-3330 processor
Genuine Windows® 8
Memory: 8 GB
Hard drive: 2 TB
So initially brought it home, set it up and fired up connected to the internet perfectly fine with the stick. Then about once every 2/3 days, it would pick up no internet connection despite being next to the router and after 2-3 shut downs in a row would work again. When the connectivity icon was blank, I would go to trouble shoot it and windows 8 wouldn't do anything, not even attempt to detect the problems (bare in mind this PC is brand new).So I leave my home by my University and came back to my parents for Christmas. Lugged my PC back with me and set it up.So first I connected to the wireless no problems, loaded up my favorite forums and after image hovering over about 3 images the 4th would only load the top 3rd of the picture. Open up new tabs "Connecting" until:
A) Server would time out
B) Wireless would DC and then reconnect (before basically repeating the "3 image view")
C) Would work for a few hours (e.g. a streamed film) before screwing up again (rare)
So, reinstalled drivers, replaced the USB wireless stick (802.11n.) AND STILL problems problems problems. I then cleared the IP/TC stacks (I believe they're called) did it through the elevated command prompt and still nothing. So i'm using my sister's laptop to write this as my internet on my PC barely runs long enough for me to be able to check this page or download the program mentioned in the sticky.

A couple of users on my network complain about timeouts. They access the same server which runs a SQL server. People from outside world can access it without a problem but internally it keeps timing out. I have also noticed that VoIP phones have a delay internally. So if i pickup my phone and dial an extension the other person can't hear me sometimes but i can hear him.
I have experienced the VoIP problem but have never had any time outs on my machine. I tried packet capture on a couple of computers but i cant see anything out of the ordinary. Alot of ARP, some STP which i think shouldn't reach the machines, dropbox traffic etc.

I have Verizon DSL. Since I've gotten it turned on in my new apartment it's been randomly DCing, I had a tech come out and tell me it was because I'm too far from the central office(thought I'm only a mile from the office?) and I needed to call and get my mbps reduced from 10, to 5. So, I called and did that and I was still having the same issue. Today another tech came out, told me the same thing, but I needed to be reduced to 3, and left. I called and got it reduced again. They said it should be 3-5 and I was at 5-7. So, now my download speed is actually higher than it was when I was 5-7(it was at 3 mbps usually, now it's 5), but my ping has doubled. Pages are taking longer to load, and when I play any games online there's a noticeable delay. I have been DCing less often, but it's still happening.

I rencently built a computer with a friend. The wireless card I had was fast but began to slow down, went from 12 mbps to just under 1. I switched cards because I figured maybe the card was bad. I now have a netis WF 2113 PCIe card. My mom in the room with the router gets 20-30 mbps while I still get <1 to 1 mbps. I've updated the drivers and looked through the net to find a solution, but to no avail.
