Cisco Wireless :: Clients Losing Connection On 871W
Nov 5, 2012
I have a problem with myself a few other clients randomly disconnecting from my 871W. It appears that I am still associated but Windows 7 shows "Limited Access". I appear to be assosciated to the AP and I still have my ip address but I can't ping the 192.168.1.1 gateway (871W). I have also set my power plan to allow for Maximum Performance which I thought disabled PSP but the log is still showing errors.As a final note, after I reconnected by ip address (192.168.1.107) doesn't show up in "sh ip dhcp bindings" but I'm working.To correct the situation, I have to disconnect and the reconnect to the AP and then I am good for another day or close to it. Below are the log errors, config and a sh ver. [code]

I know this question was asked many times, but I'm still not able to finalize my configuration on 871w. LAN part works fine, but wireless clients do not get DHCP IP. here is the config:
Building configuration...
Current configuration : 2092 bytes
!
version 12.4
no service pad
service timestamps debug date time m sec
service timestamps log date time m sec
no service password-encryption
!
[ code ].....
I'd like to have LAN and WLAN clients in same 192.168.1.0 sub net.

Any problems with the guest network on the ea4500 with the cloud firmware? I am losing guest clients after about 24 hours and the re-authentication fails. you enter the guest password and nothing happens until you reboot the router.

I've just started styding for CCNA. Bought a router 871W recently and spent two days straight trying to configure internet connection with no luck! I use console port to do the configs and SDM/CCP. How to do simple internet connection configs. I googled everything but it's still confusing. I can't assing any IP to FA ports 0 - 3. I used VLAN instead. But all tutorials use FA0 and when I try to assign an IP to FA0 it gives me some L2 can't be assigned or something... :/ And I'm also confused what IP address should I use for WAN. I plugged the cable from Modem to PC's LAN port and wrote down some IP addresses which I think I'll have to use to configure the router for internet connection. And here they are:
ISP IP: 76.114.54.255
SUBNET: 255.255.248.0
GATEWAY: 76.114.48.1
DHCP: 69.252.97.4
DNS: 75.75.75.75
75.75.76.76

I've a problem with my 871W. I can connect to the router by inside interfaces (LAN & WLAN) but not on WAN (Fa4). My client on the WAN is on the same subnet and I can ping 871.

I have an Acer 7750G, running Windows 7,connected to our home network using a Dynex router. At the moment this is the only laptop in the house that is having problems with connectivity. Starting yesterday, it only connects intermittently. When I run diagnostics, it says the following problems have been fixed but it either solves the problem for a few minutes only or not at all: "Problem with wireless adapter or access point" or "Default gateway is not available".
IPV6 connectivity also shows 'no internet access' and sometimes IPV4 reports no internet. I've unplugged and rebooted the modem and router a few times but that hasn't solved the problem.
Edit: I ran troubleshoot again, and it says the following issue is not fixed: "Wireless Network Connection 2 does not have a valid IP configuration".

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.

Im having problems with some toshiba laptops that arnt showing the SSID for some wireless points in the school. We have had the waps set up with the same ssid so we can walk around and the laptops will connect from one to the other. Its been like this for sometime however some new laptops we have got running windows 7 pro show some of the waps up as "other network" - File attached. The actual SSID on ALL waps is Peel Park WiFi Therefore it keeps losing connection to the wireless points and wont connect to some.

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.

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.

I have a Cisco Aironet c where it is configured as an AP. I use a Pocket PC to access the AP, but after a period of use, the Pocket PC loses communication with the AP for a short period of time and the application that is utilized in the pocket closes. After a few seconds it automatically connects. Searching the logs of the AP found the following warning: "Packet to client 0017.2302.8a5e Reached max retries, removing the client", but this is not always alert appears.

I have installed a wired and wireless connection for a compound which is around150 squire meters. I used the Cisco wap4410n routers for the wireless setup.
The structure is like this.There is a connection coming from the service provider. There is a central switch where the connection coming from service provider, the server, one Cisco wap4410n router and other two switches are directly connected to it. Again I connected other switches to the switches getting connection from the central switch. I used Cat 5e and Cat 6 cables to connect the switches as well as the wireless routers (For more info , the cable goes underground) and I used cross-over cable to connect switch to switch and straight-through to connect routers to switches. I connected the other Cisco wap4410n routers to the switches outside( I get like 6 Cisco wap4410n routers)The wireless routers are connected to the switches which are connected to the central switch and also on the other switches.
The routers are configured to have their default AP mode.My problem The connection is very slow. The connection is down almost every week and it needs to be re-configured. The connection nice on the router which is directly connected to the central switch(but not the same on the others routers which are connected to the other switches)even when I reset them they don't fall to .245 ( which is ok I can see them on the DHCP server but I still see it as problem)when I set them as a wireless wireless repeater, full signal but no connection(given that I have set same SSID, enabled allow wireless signal to be repeated, filling MAC addresses) Down here I have tried to show the architecture diagrammatically.

We've had this AP for just over a year and just recently it started dropping its wireless connection. To fix, I have to and unplug the power and then plug it back in.. Then it works again for a few hours and drops out again. If I navigate to the config page right after it drops, all of the settings seem to be completely gone. But if I go through and unplug/plug it in again, all of the settings are back.
I updated the firmware to 2.0.4.2, but that didn't seem to resolve the problem. Is this thing a brick now?

I recently bought a iMac and it has been fine apart from the wi-fi connection.It used to disconnect me for 2-4 minutes every now and then at first and then this died down, but recently it keeps losing connection altogether. When I go on run diagnostics it says that i have failed to connect to the ISP and internet.Is there anyway to fix this?,I use a Netgear router with an Apple iMac running with OS X Lion

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]

When using my pc through my wireless Netgear router, the connection is lost periodically and I get the message "default gateway not accessible". It only happens on my PC, and not on my IPad. What should I do to keep the connection on my PC?

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.

I have a client with an AP541n, most recent firmware installed. When he logs into the management interface (via IP using Google Chrome browser), it will work for a few minutes and then just disappear. If he attempts to reload the page he gets a message similar to a website being down (page cannot be displayed). The idle timeout has been extended to 4 hours, but this can happen at any point while logged into the interface.

Every few minutes my WGR614v6 loses connection to the cable modem though the wireless in-house is strong. Cable modem being reset does not work. Resetting netgear router brings us back online but only for a few minutes. Have replaced power supply to router and it is still occurring.We have a desktop and 2 laptops online. Also, the notebooks always drop to 18mbps while the desktop stays at 54mbps.

My LG BD570 is losing connection about 30mins in while I'm streaming an .avi from my desktop.This problem has only been happening since I setup my new wireless router. Belkin N300.I have no other network problems between my computers or simply using the internet.I did not have this problem previously when I was using an older Belkin Wireless G+ Router.

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.

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.

I have to reboot my router a couple of times per day because I lose WAN access. This occurs with both the wireless and ethernet connections. Basically, I see that I'm connected to the router, but have a self-assigned IP. Power cycling the router does the trick. I never had this problem before, so I'm wondering what's up. The firmware has long been up to date. Router version is 8.0.

I am runnong 1.0.04, have reset to factory, reflashed the 1.0.04 code and done a 30-30-30 reset (so far no drops since the 30-30-30 reset but we'll see).

I have a Linksys WRT120N wireless router that I have had for almost three years now. It recently has started dropping all internet connections very randomly, sometime multiple times in an hour. I will lose my connection to the internet and connection locally to other laptops then it will reconnect. It is also disconnecting when wired as well as I have a playstation using a wired connection out of the router and it loses connection all the time as well. What is causing this, I am pretty sure it is the router and not my internet service.

Currently I have the ea 6500 and it seems to lose connection to my IPAD 3 often. I have setup the IPAD to connect to 5ghz connection and it will still lose connection. Is this an ongoing issue? I also noticed that it signal stength isn't fully covering my home like my linksys wrt54g did.
