Wireless :: Clients Randomly Drop Off Netgear Router

Sep 20, 2011

Wireless clients drop off Netgear router - Running a Netgear router in home. Have one desktop PC, 2 printers, 1 Mac and 3 Windows laptop connected. The devices that connect wirelessly will drop of the router in a random way. One printer, an HP all in one, will no longer function and I have to pull the plug to de-energize and restart it. My wireless network is a mess. I have called Netgear and for the first two months they had me change channels and adjust other settings which seemed to work at first but then these symptoms all came back.

Wireless :: All Of A Sudden The Network Began To Drop Randomly

Mar 15, 2011

Up until recently (4 months ago) my network was fine. However, all of a sudden the network began to drop randomly. Now, the network drops about every 30 mins. Its quite an inconvenience, especially as there are two laptops, a desktop and 2 games consoles running off of the network (not all at once though). I have a Belkin Wireless G Plus MIMO router.

Netgear Dg834gb V Router - Wireless Connection Will Drop At Random Moments?

May 21, 2012

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?

Netgear Rangemax Wpn824 - Randomly Cannot Connect To Wireless Router?

Oct 22, 2011

I am using a Netgear Rangemax Wpn824 with comcast cable internet. This problem happened also on an older router but less frequent with this one.

I don't know if this is a common problem but I cannot seem to find it on the web and thought I would ask here. The problem seems to only happen after someone restarts their computer.

What happens is 9/10 times on startup the internet will connect just fine but the 10% of the time it will say "Unable to connect to Shaun" (my wireless router) Sometimes if we restart the computer it will fix itself but usually we have to reset the router and it will fix itself and wont happen again for another couple of weeks.

I called comcast about it and their tech support said it was a router issue, that's when I put in my newer one (the rangemax) and its still happening. We even upgraded the comcast modem recently too, and since it fixes itself when I reset the router I don't doubt its the router.

I can't seem to update the firmware on it, not sure if that will work. (It says not enough memory to complete) Should I buy a new router?

Home Network :: Using A Netgear WG602 Wireless Router - PC And Iphone Randomly Losing Connection?

Jun 2, 2011

Currently using a netgear WG602 wireless router which i use to connect to my 2nd PC and Iphone, with the Netgear router running from my main PC.I have recently been having trouble with my 2nd PC ad Iphone randomly losing connection and the only way for the connection to be reastablished is to reboot the wireless router. Once rebooted i am able to connect again to the internet with no problems, interestingly enough my main PC never loses connection. Also sometimes when i lose my connection and reboot the wireless router i will have a IP conflict pop up on my 2nd PC however i would i say i get this once in every 10 dissconects and not all the time. Sometimes i won't dissconect at all in a day but sometimes i may dissconect 5-6 times.

Cisco Switching/Routing :: 6500 - Randomly Devices Will Drop Offline And Then Come Back

Aug 28, 2012

I have a network that has a pair of 6500 switches on either end, running HSRP. In between each 6500 are two to three ruggedcom switches. They are connected to each other and the 6500's by trunk ports in a straight line. The 6500's see each other as CDP neighbors, and the 6500's can see the rugged- com as LLDP neighbors (ruggedcom only supports LLDP).
 
The issue is that randomly devices on the ruggedcoms will drop offline and then come back. The problem is that the devices that drop offline are all in the same VLAN, so it appears like a virus -  i.e. one device drops off, then multiple. Eventually the HSRP starts flapping between the two 6500s and this causes havoc on the network.I'm almost to the point of taking a laptop and plugging it into one of the ruggedcom's to see traffic, but the issue is that the ruggedcoms are outside in cabinets that laptops shouldnt be exposed to.

Cisco Switching/Routing :: WS-C2960S Output Drop Values Change Randomly

Oct 19, 2011

I have a stack of 4 Cisco WS-C2960S-48FPS-L switches running c2960s-universalk9-mz.122-58.SE1 code.  One of our network monitoring tools is indicating discards on a certain port on the switch.  Upon further investigation I am seeing the Total output drops values change in a very odd manner.
 
The numbers seem to go from 573 to 1146 to 1719 then back down to 573 and it starts the same pattern over: [code]

The port utilization is quite low, the highest I've seen over the past 7 days is 3.5% with a polling period of every 30 seconds using Statseeker.  Yet the discards are bouncing all over the place.
 
I've searched though the bugs for 12.2(58)SE1 and didn't see anything.

Netgear WNDR4500 - Clients Not Showing Up In Clients List

Jul 6, 2012

I have a Netgear WNDR4500 running the stock firmware, acting as a router for my home. I also have 2 routers that are flashed with DD-WRT (Linksys WRT54G and Asus WL-520GU) running as client bridges. The Netgear is 192.168.1.1 and the other 2 client bridges are 192.168.1.2 and 192.168.10.3. The Netgear router is performing DHCP giving addresses from 192.168.10.100 to 192.168.10.254. I have numerous machines connected to the Netgear, wirelessly and wired, and numerous machines wired to each client bridge. All machines have IP addresses that are 192.168.10.100, 192.168.10.101, 192.168.10.102, etc... Everything is working fine, but I have one question: When I access the Netgear router, it shows the client bridges as clients, machines that are wired and wireless to the Netgear router are listed as clients, but the client list does not show any clients that are connected to the client bridges. I assumed that since the router is performing DHCP that all clients would show up.

Netgear WG111 V3 Adapter - Disconnected From The Internet Randomly?

Feb 18, 2013

The problem is basically that my home wifi runs from a router that renews its IP adress every hour or so, and I keep getting disconnected from the Internet for 15 mins. or so every single time and then again not always; sometimes a page fails to load and then the connection is re-established a moment afterwards - it's very random.

The odd thing is that while my desktop Pc gets disconnected for long peiods of time my PS3, phone and laptop all seem to be able to reconnect during other periods of time where the desktop is unable. Also my parents and sister seem to be disturbed in different intervals. This makes me think that besides the annoying short disconnection on every device, my wifi adapter might cause the desktop additional problems reconnecting.

I'm using a Netgear WG111 v3 adapter. I should probably note that when I was running Windows 7 it already gave me trouble installing drivers and I had to run compatibility mode for Vista, and now with Windows 8 Pro 64-bit I had even more trouble, installer crashing and me having to manually go to the Device Manager and search for the install data for the driver. It's only been causing me problems since I bought it and though it works as I write this there is no way for me to know if it goes offline again or not in the next second.

I've recently reformatted my Pc and that didn't change a thing in this context and I've also been in contact with my Internet provider (the largest of such in Denmark, where I live), and they are the ones that told me that the router needs to reaquire a new IP every now and then for security reasons.

RT-N56U Wireless Drop Every 5-10 Minutes After Router Rebooted

Dec 25, 2012

There are three RT-N56U routers in my family. I have one as does my dad and uncle. Bought all 3 about a year ago. They've been rock solid since.

However, my dad has been complaining of network issues, mainly lag and slow response. During Christmas yesterday, I took some time to troubleshoot it which ended in disaster. He was on an older firmware so I had updated it. After the update, the wireless would drop every 5-10 minutes after the router rebooted. I tried rolling back the firmware and there is still the same issue.I reboot the router, wireless comes up and within 10 minutes, the wireless is down.

Most of the clients on the network are iDevices. There are two iPod Touches, 4 iPad Mini's and iPad, two iPhones and an Apple TV, all wireless. Other than that, there is a PS3 and a bunch of wired clients. Looking in the routers logs, it appears that at least one device keeps requesting a DHCP request even though it has an address. Then at some point, the router spits out this error in the log: [code]

That error just keeps counting up, starting at 1 -- Based on google info it's related to wireless drops due to ASUS firmware issue with certain wireless cards. My guess is one of the new devices has a card that they don't support, causing this issue. I was stating to think, since he has so many iDevices on his network, an Airport Extreme?

Linksys Wireless Router :: WRT120N Drop Internet Connection

Sep 13, 2011

I’ve bought a router, and a wireless antenna for my laptop, since I have a high-speed internet outlet in the living room, but I use my laptop in the kitchen (I don’t have any other pc). So I’ve configured my Linksys WRT120N router in the living room, unplugged the ethernet cable from my laptop, plugged the wireless antenna in the kitchen, and everything was working fine with the wireless network. After about one month I was not able anymore to enter my network with the security key, there was actually no prompt for the security key, just a message “Cannot connect to the network”. I then had to reconfigure the router, going to the router IP address (I used the default settings, a blank for username, and “admin” as a password, as per instructions), use another network name, security key and password, and was able to start again a wireless network with the wireless antenna as before. This problem represented other 3 times (in the last 3 months), and was working fine, but now I cannot reconfigure the router anymore, since the IP address doesn’t accept BLANK/ADMIN anymore, and if I go ahead and reconfigure the router a message says I have to use the default settings in the IP address…

Linksys Wireless Router :: WRT54G2 V1.0 Devices Would Drop Repeatedly

Apr 5, 2012

I purchased this router a few months ago(wrt54g2 v1.0) when I moved into st louis missouri. My ISP is charter communications. I am using windows 7 64 bit.I had no problems with this router with wired connections, however my wireless devices would drop repeatedly. I updated the firmware to the latest linksys version, but still same issue.After much research online and trying everything I could through linksys, I found a page that someone with the same problem said it could be solved by upgrading to dd-wrt freeware firmware. After much trials and problems, I finally got it installed. However I did not like dd-wrt because it would not allow FTP access no matter what i tried, and would lead to dropouts of wired connetions even though it did fix the wireless.I then decided to revert back to the previous firmware - this is where i think i messed up..I downloaded tftp and a firmware called vxworkskiller, this was supposed to be able to break the dd-wrt firmware which it did, and removed it. I continued to follow the instructions provied to me and was able to then install the linksys firmware but I accidentally upgraded the firmware for the router WRT54GS with the firmware version 7.50.2. This is now dropping both wired and wireless connections VERY frequently. My roomate is not happy as we have to power cycle the modem, router and pc's every couple of hours and sometimes that doesn't even work.I am unable to flash firmware of any version or type anymore, every upgrade fails weither I use the linksys gui, or tftp or any previously working firmware. All fail.

Linksys Wireless Router :: E4200v2 Xbox Drop About Every 15-30 Minutes

Feb 23, 2012

I have 3 devices connected to the e4200v2 via etherent, out of the 3, only my Xbox has drop about every 15-30 minutes. I have tried Cisco customer service 4 times and Xbox customer service 3 times with absolutely no luck. They both tell me that all of my setting are correct and there is nothing more that can be done.
 
I have tried everything that I can think of: Port triggering, port forwarding, DMZ, UPnP enabled/disable, power cycling everything, putting Xbox as Qos high priority, designating a static IP for the Xbox, clear the Xbox's cache twice, I even formatted my Xbox's hard drive in case of corrupt data. The Xbox does not disconnect when connected directly to the modem, making the router the common denominator. I am on the verge of returning the router.

Linksys Wireless Router :: E4200 Speed Drop Using Ethernet Cable

Oct 4, 2011

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?

Linksys Wireless Router :: WRT110 Internet Connection Will Slow Down Or Drop Entirely

Jan 8, 2012

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.

Linksys Wireless Router :: E4200 Wireless Client Drop On Transferring Data

Dec 14, 2011

I have had an e4200 for about a month now and its been pretty good.  But I have noticed that it completely locks up when I go to copy mass amounts of data through it.    I have a NAS drive plugged into it and my laptop is on the 2.4 spectrum.  I went to transfer 8gigs of data from laptop to NAS drive and the entire wireless portion of the router locks up.  All my wireless clients drop and I have to unplug the router and plug it back in.    Even the 5ghz clients drop as well.  I have not tried hardwire, but the main reason I got this was for its throughput.

Linksys Wireless Router :: Wrt320n Wifi Connection Drop When Internet Connected

Oct 11, 2012

I have experienced some strange behavior of WiFi connection using WRT320N router. ISP provides me the internet in 2 modes (day and night). During day mode max speed is 24 Mb/s and during night 60 MB/s. Modem ADSL (Cisco EPC3010) is connected to Linksys WRT320N and on router is configured WiFi.Now issue. In the day mode everything is perfect. Cable connection gives me 24 MB/s and WiFi connection around 22 MB/s so not so bad.  However when my internet speeds up to 60 Mb/s (cable connection via router gives exactly 60), WiFi connection instead speed up as well, just drop to max 17 Mb/s. I have tied several different settings on the router including changes in WiFi band, channel width, different channels (now channel is setup to 1 which is maybe not totally free but no so occupied) and others but unfortunately without significant improvement (in many cases connection just slowed down more).

And some details:
Wireless configuration (now)
Band: 2.4GHz
Mode: Wireless-N only
Channel Width: Auto (20MHz or 40 MHz)
Channel: 1

Wireless adaptor:  Intel Centrino Advanced-N 6230 (I know that this doesn’t mean anything but Win7 shows that connection is established with speed 144MB/s)Router firmware and WiFi card updated to the newest version.

Linksys Wireless Router :: EA4500 Drop Signals On Fairly Regular Basis

Nov 13, 2012

So here's my issue, I just bought this EA4500 so I could use the 5.0 Ghz and get a new 2.4Ghz as my old Netgear would drop the signal on a fairly regular basis. I've set the channel on 2.4 to 1, 20 Mhz Channel, and my neighbors are for the most part using channels 6 and 11 (one guy is using channel 2 at 40Mhz but has a very low signal strength). The signal drops out sometimes as often as every 5 minutes, and now it is doing it on my new router. Here's the kicker, the 2.4 band falls out from my router and some of my neighbor's routers, no new signal seems to come up, but the 5.0 band on the EA4500 is just fine, as is the wired route. Is the 2.4 band just being assaulted at my home and I'll have to deal with it, or is it that my new router, old router, and my neighbor's routers, all suck, and we should all get refunds? Any solutions to troubleshoot this beyond running a netstumbler like software, setting hard channels (including width), and long hours of trial and error? I am running this all from my macbook air, the 5.0Ghz is at 40Mhz, is the only signal, and is on a fixed channel.

Wireless Router Randomly Locks Out Devices From Connecting

May 30, 2012

Wireless router started randomly not allowing any wireless devices to connect to the network. A wired cable worked fine, but not wireless. So we had to unplug the router and then it would work fine.You could see the device, but not connect. We moved our wireless phone a little farther away from the router thinking it was interfering, but still no luck. It didn't matter if it was an iPod, our BluRay player, or a laptop.

Linksys Wireless Router :: E1500 Disconnects LAN Randomly

Jun 1, 2011

I recently purchased the Linksys E1500 and at first, had no problems with it. The last few days I've had issues however. I tried logging into the internet and my WIRED computer would not connect. My wifes WIRED computer next to mine didn't have any trouble connecting. Resetting my computer didn't work. I had to cycle the router by unplugging it! Then today, my (2) kids are using Pandora on their (2) computers wirelessly, and same set up with my wifes computer and mine, and again only my computer looses access from the router and all other computers stay connected.

Linksys Wireless Router :: E4200 Changes IP Range Randomly

Oct 4, 2012

About a month ago, my E2000 Cisco Router stopped working, just after warranty expired (how awesome!) where as either WiFi worked or Wired but not both. I know Cisco will normally grant you a grace period (from experience) but sending it to the Czechs and pay for postage.. wait 4 weeks and then have internet again.. is not an option (did that last time)So this time.. I spend a bit more and bought the E4200. 4 weeks later, the IP changes from a 192 to a 17x .. pretty anoying when being abroad and needing to access the NAS since you do not know what IP it took.. I restored the config upon return.. and all seemed normal again and I left for the next trip. One day later (today).. again.. no connection.. wife has internet she says.. so again the same issue.. the **bleep** thing took another IP.

Linksys Wireless Router :: Wrt54gv2.0 Wifi Turns Off Randomly?

Mar 3, 2013

Apparently when watching TV after the show is over and the TV is turned off the lights on the router dims and their wifi router is not able to be found any longer and they have to reset the router in order to find it again. I downloaded the newest firmware version 4.21.5 yesterday since they had the original firmware from years ago thinking this may solve the problem. It worked for a day and then stopped with the router having the same symptoms. They have this router located very closely to their plasma TV for the past 3 months, however, I was reading that wifi routers do not cause any interference with plasma TVs. They had this router placed near their old rear projection TV for years and never had any problems.Could the router be going bad? Could the router be too close to the TV?

Linksys Wireless Router :: E4200 Randomly Reverting From 450 To 300mbps?

Feb 25, 2012

I've got this weird problem with my E4200 in that I've set everything up to get the maximum 450mbps link rate, but it randomly falls back to 300mbps and I don't know why.   I can get it to connect at 450mbps again if for example I go into the wireless settings and toggle the channel that is used, or if I go into QOS and disable then enable WMM, but it seems that after a period of time that the router goes back to 450mbps anyway.
 
I'm not sure if this is an issue with the router or my wireless card.  I'm guessing it's the router since inssider reports the max link rate at 300mbps at times despite it being set up for 450.I'm using firmware 1.0.01 as there is a bug in later versions that means the WAN port cannot transfer above 80mbps. My wifi adapter is an Intel 6300.
