Keep Losing Wireless Connectivity?

Mar 30, 2011

Noticed the last couple days that pages weren't loading on my laptop. Looked at the network status for the laptop and noticed that my network speeds would fluctuate from 54Mbps to 1Mbps, and various speeds in between. I had never had this happen before (I've had this router, a Linksys, for about 6 years). I thought maybe something was going on with the laptop. Grabbed my wife's laptop and she had the same issue. So, I checked the wired towers - their speeds are running at 100% all the time, no fluctuation. So, it has to be something with my router, but I'm not familiar with how to diagnose, etc. The router has a 3rd party firmware (DD-WRT) flashed on it, in case that matters. But I've had that on there about 4 years, nothing new. I've done a DHCP release and renew.

D-LINK DIR-625 / Randomly Losing Wireless Connectivity

Apr 4, 2011

I have a DIR-625 router that has been acting odd lately. Several times a day at random my devices (laptop, android phones, PS3) will lose internet connectivity from my wireless network. They say they are still connected to the network but I am unable to access the internet or even the router config page. Everything works fine on Wired LAN computers. The only way I can fix it is by unplugging the router for a few seconds. I have had the router for over a year now without this problem. Seems like it may have started when we got our android phones.

Cisco Wireless :: WLC526 And Two AP521Clients Keep Losing Connectivity

Jun 24, 2012

I have a UC520 in a building with several IP phones.  We installed a WLC526 and two AP521's for seamless roaming of cordless phones.  THe phones work great with no issues.  When I am running a ping test on a wireless laptop, i keep loosing packets.  It looses connectivity randomnly.  DHCP is given via Windows 2008R2 server.  Have a cisco 2948 switch also in the mix.  THe AP's are connected directly to teh front of the UC520. Why do phones work perfectly and not data?

Cisco Wireless :: 1252AP Losing Network Connectivity

Sep 7, 2011

our autonomous 1252APs. It loses network connectivity irregularly and ends up disconnecting everyone. It may stay up from a few days to a few weeks. I don't see any log messages that give any clues to why it is doing this. We have 30 of these working worldwide (on the same software level and same config) and this is the only one having the problem.
 
Things I have tried: Changing software levels - there is a code level where it didn't seem to have this issue, but I can't run it because then I'm unable to monitor it in our monitoring system. Swapping out wireless access pointsRe-terminating the cable on the AP side, it was really difficult to get the network cable into the AP while swapping it outBlocking a company test piece of equipment from connecting using the mac address filtering (it connects with one of their test IPs - weird) – I still see it connecting though I don't see high utilization on the switch port when the issue happens I had a few cases open with TAC, and they were unable to find anything wrong - gave them sh techs of prior to the event and after the event. It was one of those where the tickets were open for a weeks with no updates.

Cisco Wireless :: WLC 5508 Implementation - Some Users Losing Connectivity

Dec 3, 2012

We are implementing a WLC infrastructure in our company following the below scenario:

- WLC 5508, OS 7.2
- APs AIR-LAP1142N-T-K9
- 3 Wlans (1Open w/ Web Auth, 1 WPA2 and 1 802.1x)
 
Issues:Everything seems to be fine, but some users loses connectivity (when connected to 802.1x network) at least 3 times by day.

- I cannot see anything at WLC logs concerning the association/deassociation of any of these users.

- Only strange line in the logs is "RADIUS server 172.21.44.50:1646 deactivated in global list" (authorization server config)

- Also I see some "Coverage hole pre alarm for client" but that doesn't look like a problem...

Cabling / Cards :: Belkin F5D8053 N Wireless USB Adapter Losing Connectivity?

May 18, 2011

I recently purchased a Belkin F5D8053 N Wireless USB Adapter after my 6 year old adapter was unable to see my home network in the network list.

I installed the software but the adapter wouldn't connect to my home network so I reinstalled and updated the driver, still wouldn't work. Finally about 2 hours later it just randomly connected. Now it has been frequently (1-2 times a day) losing connection to my home network for around 3 hours, it can see a dozen networks in the list with full signal strength but won't connect to any at all then connects to my home network again several hours later.

I have switched between the Windows connector and the Belkin one and tried all 6 USB slots with no luck. I contacted Belkin support and they told me to try the device on another computer and see if the problem still happens but I don't have another computer to test it with.

I suspect this is a problem with my Windows installation rather than the hardware or router as my old card would freeze once every couple of days and was only fixed by powering off my computer as Windows was unable to kill the process to restart it.

Linksys Wireless Router :: E3000 Losing Wi-Fi Connectivity On Multiple Device

Sep 7, 2010

Issue with Linksys E3000 router (firmware 1.0.02). I'm experiencing issues with the following wireless connections:
 
-iPhone 4G (wife's)
-iPod Touch 2G
-PC with wireless connection (non Linksys brand adapter)
-Acer NetBook (non Linksys brand adapter)
 
The issue is the connection gets interrupted and dropped, but the devices and the router DHCP clients table show the connections are still present. By interruption, I mean no data traffic is being transmitted.My wife's iPhone 4G and my son's iPod Touch wifi both show they are connected to the home network, complete with wifi bars being displayed, and the checkmark is present next to the home network connection in the the device settings for both. When I check the E3000 DHCP clients table, both Apple devices are listed as holding a connection. Yet both devices display network errors when trying to use any app that connects to the internet. By restarting the wifi connection on each, the connection is restored to the point where traffic now transmits. My wife and son estimate it is after about 10 minutes that they encounter the interruptions.
 
On the PC and NetBook, the connections have to be terminated and reconnected. I have not timed these to see how long before the connection becomes problematic.Interestingly, my ASUS laptop and my iPhone 4G do not have the issue, nor does my work laptop (Dell).There are no timeout parameters in the router config. Closest thing to it is the Beacon Interval, but I don't know which way to adjust it (up or down) to manage the devices that are experiencing interruptions. I have not made any interval adjustments...at this time, everything is set to default settings.This E3000 replaced an aging WRT54 (hardware v2) router so that I could have an N router in the house.

Keep Losing Internet Connectivity?

Aug 29, 2012

ISP : ShawPC >> SMC Modem/Router >> Netgear Router >> PS3 and Denon Stereo Receiver ( Both hardwired to Netgear Router), 2 Laptops and 2 Phones connected wireless- The reason I do not use the SMC as a router is because I was getting terrible wireless signal- When everything is working properly I am getting great speedsroblem : I keep losing internet connectivity. On the wireless devices I still have have great signal strength but no connectivity. I need to run netgear genie oripconfig/release/renew to get it back. It always comes back but this is annoying.It also does this on the PS3 and Denon which are hardwired to the router..as with the other ones if I reset the router or do a connection test on the PS3 it will fix it. Finds IP but no internet connectivity.My PC has also started to lose connectivity and I need to do a ip release/renew and it comes back fine.The fact that this is happeneing on my PC would lead me to believe that it may be an issue with the Modem/router. Are there some settings I need to change on it since I am only using it for modem purposes? I have disabled the wireless on it but I don't think that would be the issue anyways

Realtek PCIe FE Losing Connectivity In Windows 7 Home 64-bit?

Losing Connectivity Every Couple Of Hours / Modem Or Router?

Sep 19, 2012

I have an issue with my current network where every couple of hours I will lose my connectivity and it will not come back unless I do a power cycle on my router/modem. I originally thought the issue was with my router, however I'm beginning to think it's an issue involving the modem. I've tried two different routers and this happens on both. My main router is a D-Link WBR-1310 (crap I know but it was free) and has lasted for years, and my modem is a Toshiba PCX2500 from Time Warner Cable. The second router I used to test this was an older Linksys BEFW11S4. I was going to replace my router, but when I saw that both of them reset after a few hours (today was only 5, last night it was connected for over 8 hours as I slept). I ran an IPCONFIG /ALL when I was connected with internet and when I was connected without and the only three changes were: [code]

Network fixes I have attempted from the OS level so far include:

~ Switching the dynamic port range to start at 10,000 and run for approximately 54,000 ports

~ Systematically reviewing every running service to make certain that only the essential ones are on

~ Disabling all NIC stacks except Client for Microsoft Networks, IPv4, File and Printer Sharing and Comodo

~ Attempted connections with Comodo turned completely off and its NIC driver disabled

~ Attempted rolling back the RealTek driver to an earlier one from the same family and device line

Using netsh I have tried the following settings:

~ netsh winsock reset catalog
~ netsh int ipv4 reset reset.log
~ netsh int ipv6 reset reset.log
~ netsh int tcp set global rss=enabled

Laptop Losing Wireless Connection?

May 30, 2012

So my boyfriend and I just moved and, after struggling with our old wireless router we haven't used in years (pretty sure it was dead), we bought a whole new one in the hopes that starting from scratch would be simpler. It's a Netgear and we were aiming to hook up three devices through it; my laptop, his computer, and our Xbox 360.

He hooked it up no problem and we were using wifi for our computers and one ethernet cable through the router into the Xbox, peach as pie... Except my Toshiba laptop decided to rebel and allow me to use the internet for about five minutes before claiming there's "no internet." The signal says excellent and the little alert symbol keeps appearing and disappearing, but no pages will load. I tried running troubleshooting, but it couldn't identify the problem. Shutting down my laptop and turning it back on seems to be the only way to get it going again for another five minutes until the cycle continues.

Losing Network When Some PCs Try To Connect Wireless?

Jun 15, 2012

I've got a linksys router with two desktops running on it fulltime. One is hardwired (Win 7), the other is wireless (Vista). Normally, they have no problems with connecting. But I just got a laptop (Win 7) that is causing the whole network to go down for about 15-20 minutes then it will come back up for all my PCs but still drop out sporadically causing another 15-20 minute wait Both my desktops are unable to connect during this time. I also just got an old refurbished XP laptop from work, and it connects flawlessly. Then we had a friend come by and try to connect to our network and her laptop had the same problem.

Losing Wireless Connection During TV Playback

Oct 8, 2011

I am running the below rig and connecting wirelessly via my DSL Router to my Blu-ray player which is connected via HDMI to my TV. Using Windows Media Center I have been recording shows via an OTA antenna. They are in .wtv format and going on the 500GB HDD. Playing these files on my TV has been going well until this week. During playback we frequently lose the connection. I have tried power cycling the router and the player, re-entering my settings in the player and connecting via Cat 6 cable. The only clues I have are that I recently did a second firmware update on my player (did not occur immediately after that) and I sometimes get the following message on the computer... Media Foundation Protected Pipeline EXE has stopped working.

D-Link DIR-655 :: Keeps Losing Connection Through Wireless?

Mar 5, 2011

It seems to happen only when connected through our rooms or through wireless.  When I connect directly to the router I don't lose connection.  The router is downstairs and it routes the wired connection through a switch.  So when routing through the switch or using wireless the connection is lost and re-connects about every 30 seconds to 1 minute.  When directly connected it works fine.  I've reset the router and reset all settings twice and nothing.  I'm using 10/100.  Not sure if any of this matters. I have also updated the firmware to 1.35NA.  PPPOE password and username are correct as they have been given by our ISP.  Any settings I should be aware of?  Everything is pretty much default.  All I do is setup the internet connection and then setup a wireless connection.  Are we overloading the system maybe? I've also changed the password a few times as well.  Seems like the logs fill up really fast. Keep getting blocked UDP and TCP packets from different addresses.

Intel Wireless Card Keeps Losing The Connection?

Jun 13, 2011

my Intel wireless card keeps losing the connection. Until a couple of weeks ago it would be fine for roughly the first 20 minutes then the connection would just completely drop out and the only way to get it back again is to go into the network and sharing centre, disable the network card and then reenable it. Most of the time this works, but again for only the first 20-30 minutes, then I have to do it again. Occasionally it works for for longer but that's a rare occasion.Now not only does it do this, but also, if I put my laptop into sleep, sometimes when I turn it back on again the card will not connect to the network and I have to do the same disable and enable process.[ODE]

PCI Wireless Adapter Constantly Losing Connection?

Jan 24, 2012

Im currently living downstairs from the router. Its in a "secure location." Long story short, the person I live with is very private about the particular room its located in. I know the router is a "N" model Linkys.I installed the software that came with the PCI adapter (NETGEAR N300) and everything seemed smooth, then I constantly kept dropping connection. I then assumed the driver needed updating so I uninstalled the driver and re-downloaded the recommended driver from the netgear website,Things to know:

-I don't do any heavy gaming

-When I disable and reable the PCI adapter driver from device manager I can reconnect to the internet rather quickly.

-When uploading a video to youtube I found the connection to be more stable, but slower. (could of been a coincidence)

Currently I've been running "TCP view" to try to find something in the background taking bandwidth. I searched all the applications that it lists and nothing seems to be abnormal.

D-Link DIR-615 :: Losing Wireless Connections To Devices?

Feb 5, 2012

My Dlink router has been working fine until recently.  The only changes I made was to try to put time limits on my kids' devices, through Tools->Schedules and Advanced-> access control. Things worked Ok, but I soon realized I had to reserve each kids' device DHCP number, or so I thought(?)  Anyhow, now I seem to have to log into my dlink router weekly as their wireless connection stops each week.  Not sure if it affects the non-reserved wireless devices. Not sure what's happening or what I did wrong.  Running the following: DIR615 hardware Version B2 Firmware 2.25 Under DHCP Server settings: Enable DHCP server - checked Addrss range 192.168.0.100 to 192.169.0.199   Note - reserved ips in that range Lease time 1440 minutes Always broadcast - checked rest blank NetBIOS type Mixed mode.

Linksys Wireless Router :: WRT54G2 V1 Is Losing Connection?

Aug 9, 2011

I bought a Linksys router last summer for my PC and Xbox. The PC and XBox are hardwired into the router. About two weeks ago, my router began dropping connection throughout the day. Sometimes it happens 3+ times in an hour. Other times it works for several hours before it drops.I upgraded the firmware as one fix and did a hard reset of the router. Still drops connection.I changed the MTU to 1400 and it worked fine for several hours but then dropped again the next morning. Also, like others on the forums, when I changed the MTU and hit Save Changes, it just ran and ran, never timed out...but never showed that it finished the command to save (if you get my meaning).I downloaded the Cisco Wireless Magic program to troubleshoot. It tells the same thing everytime. Unplug your router for 10 seconds and start over...My PC sometimes flashes a warning when I am restarting the router that I am getting Limited or NO Connectivity.

D-Link DIR-655 :: Not Broadcasting Wireless / Losing Internet Connection

Oct 25, 2011

I bought a DIR-655 about 8 months ago. I had no problems connecting to the internet for the first couple of months. Then I would get a random connection problem where I would reset my modem or the router and all would be fine for a while. Then about a month and a half ago it started getting worse and worse and about 3 weeks ago it got to a point that I was resetting the router or modem daily to get a initial connection to the internet. And that would last until the next day when we would try to access the internet. Ocassionally, if I had a good initial connection, I would get a random loss of the connections a minute or two after I started surfing the web. Initially a modem or router reset would clear this up too. This happening both over wireless and through the hard wired connection. So it doesn't matter how I am using the Router. AND, most recently resets may not even get me a solid connection to the internet. So, I have bypassed the router for now.

The router was set up with changes to only passwords, network name, a changed router IP address and not broadcasting the wireless it has worked fine. After the reset, I left the router IP address as the default but changed the above security settings. Nothing else was changed. I have never had any issues logging into the router menus through the default or my defined IP addresses.

In doing some troubleshooting, I performed a reset on the modem several times, none of which resolved the problem, I was still losing the connection. Then I bypassed the router and did a direct connection to the modem and all is good and I have not had a connection issue since. I even tried changing the Ethernet connection on the back of the home computer to a different computer port but that changed nothing. I am currently trying a different cable. I am using the standard connection scheme:Cable from outside to modem, modem to router via Ethernet into the proper router port, Router to static computer via Ethernet. And a laptop accesses through the wireless. All cables have been working fine and are home built CAT 5e cables

It is really frustrating and I am not sure where to start now. Currently, I am running without the router for internet but I need it for the wireless to a laptop in another room. I use Time Warner Cable and have a Atlantic Scientific DPC2100 cable modem.
