We have a Cisco 1142 AP which has been suffering chronic connection drops to Mac OSX clients.
Sometimes clients go for days without an issue. Other times, connections drop several times within a 15 minute period. Problem seems to be independent of location with regards to AP. It happens when the client is within 20 feet, visual sight. [code]
What's wrong with this config ? Clients can see the wireless ssid's but cant connect.

Clients are randomly getting dropped with "Limited Access" shown in Win 7. In this state, the client machine is unable to ping the gateway and sometimes lose their DHCP assigned IP as well. A manual disconnect/re-connect to the SSID is required everytime.I ran a debug on one the clients stuck in the "Limited Access" state (debug client xx:xx:xx:xx):

We are about to upgrade our training facilities wireless and i have a few questions regarding the number of active clients we should target our design for.
We would be using 1142 and 3502I access points. I was thinking that based on the belo we'd be able to support around 30-40 clients per AP.

I am trying to setup two Cisco 1310 bridges (AIR-BR1310G-A-K9-R) for connectivity between two buildings. No external antennas have been setup yet and I am just setting the basic configuration.One is running c1310-k9w7-mx.123-8.JEA3, the other c1310-k9w7-mx.123-7.JA1,setup as a root-bridge, the other as a non-root bridge.However, even after disabling authentication and encryption, both units are still not talking to each other.Maybe a second set of eyes can see an issue?
View 7 Replies View RelatedAs I posted about in the other AP541N thread about degraded performance, mine did a strange client disconnect last week. It dropped all authenticated clients, but they all thought they were still connected. A quick disable/enable of the wireless card on the laptop would get the computer back on the AP.
This same thing happened again today.
Device information and configuration:
Device: AP541N
H/W: V01
[Code]......
I have an AP541N-A-K9. For the past couple weeks it stops work at 5:00pm. The clients can see the SSID but when they connect it fails. The only way to get this to work again, is to set the radio to 5GHz 802.11N. Setting the radio to anything else does not allow the clients to connect.
I have some older clients so I need this broadcast G as well.
I have upgrade the software to AP541N-K9-2.0(1). Does not make a difference. Reset to Factory defaulst and reconfig does not make a difference. There are no Rouge AP's in the area.
Between the issues these have passing DHCP from a Windows server and now this, I'm thinking these devices are not fully baked.
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]
View 7 Replies View RelatedWe have a 4410N that all the time drops the connetion. We have approx 25-30 users using wireless. But when they try to connect or are connected, the router drops the connection like a yo-yo. The firmware is updated with no difference.
The wireless connection is very unstable. It's configured with WPA2 Personal and is connected through a POE-switch with IPv4. The logs don't answer the questions why it drops the connection.
I am using a desktop computer and have the router downstairs so I am using a wireless usb to connect to the internet. My router is a Linksys E1000 and the wireless adapter is a Netgear WG111v2. The problem is Every few mins I drop connection for may 5-30 secs and then the internet is fine. During that time it does not say I only have local connection or anything like that it constantly says I have internet connection even when I dont. It is very noticable when i am playing an online game on my computer. I will get a few mins in and then it will drop kicking me out of the game and by the time I get kicked out my Internet is reconnected and I can join again.
View 8 Replies View RelatedI recently bought a new HP Pavilion dv6 Notebook PC and have been experiencing problems when connecting to my personal wireless network. It seems that whenever I'm downloading anything or using the connection extensively I'll lose internet connection and the wireless icon in the bottom right hand corner of the screen will show an orange star to indicate that connections are available. However if I go to available networks I can immediately reconnect to the network I was on.
I have other notebooks that run on XP that do not have this issue and use the connection without a problem. Also when I connect my notebook directly to my belkin router via Ethernet cable the connection has issues. I'm running my computer on Windows 7 Home Premium 64-bit and my Wireless adapter is an Atheros AR9285 802.11b/g/n Wifi adapter which appears to have up to date drivers.
I already have an existing wireless network set up. Since buying a laptop the internet wireless connection drops out from the laptop after 'sleeping'. I then have to troubleshoot to get the connection back again.
View 1 Replies View RelatedWe have 2 AIR-WLC4402-K9 devices at a remote location that will both drop their network connections some undetermined time after a reboot. We cannot reach them via telnet, SSH or HTTP. In fact, we cannot even ping them once they drop connection. The only cure we've found so far is to power-cycle the controllers. The controllers are in separate rooms and connected to separate switches. We've confirmed the links are configured as trunks and have the correct speed/duplex settings. I tried updating the IOS & boot loader on one of them but that had no effect on the problem.
View 19 Replies View RelatedI am trying to track down a problem I am having with one laptop. Other wireless devices on the network are not showing the same problem. Connecting to the router by ethernet resolves the problem.Over a 120 second period, the wireless connection drops and reconnects several times. Each time it drops it almost immediately picks up and re-connects. The "down time" is usually between 5 and 20 seconds.I have updated the driver for the wireless card (it was out of date) but this did not resolve.
Reading posts here - I see you typically need to see a WiFi inspector screen shot - which I have attached. You can see a couple of "drops" on the graph.
My wireless connection randomly drops, or has no Internet connection, or says it has connection and Internet but no web pages load. Usually, what happens is it says I have no Internet connection. I have to disconnect and reconnect to get the Internet back. My ethernet connected computer never loses connection.
I am running Windows 7 with a Realtek wireless card. I have updated the driver to the latest. The wireless router is a D-Link 615 e1 using DD-WRT. The router is hooked up to a Brighthouse Arris TM402G/110 modem for internet access (note: this is my second modem. I had the same problem with another modem. Unfortunately, I don't remember the name.)
When the router is connected to a U-Verse 2Wire 3800HGV modem/wireless router (with the wireless turned off) I have no Internet disconnections. Everything else is the same (I just move the Ethernet cable between the two modems). Of course, one is just a modem and the other is a NAT router/modem.
I noticed that the wireless connection has a weaker signal when connected to the Brighthouse modem then when connected to the U-Verse modem. I therefore tried to up the TX signal strength on the router. This improved the situation (and the signal strength) but I still get disconnects. I also tried setting the MSS to 1492.
Been searching threads here and all over google. I have DSL thru Century Link.Router is Zyxel pk5001z. 2 laptops being used. ( well, they were until my MB fried out.) My laptop has Win 7, my girlfriends has Vista.- Dell inspiron 1525. Only had the service for about 2 mo's. My laptop was working fine wirelessly. Hers drops constantly.Currently hers is the only one being used.Sometimes shows the red x, other times just local only.- Drops and reconnects within seconds. I have set channel to 6 and 11. disabled IPC 6 in laptop adapter, uninstalled/reinstalled wireless card in device manager, checked for newer driver, checked for firmware upgrade in modem, set to g/n only, ( no option for G only) connection strenth is full. No wirless phones, no close neighbors, etc. I have read posts indicating the routers are junk, other posts saying Vista has issues with certian routers, but nothing that pinpoints my exact problem. Also, just re-loaded Vista the other day.

View 1 Replies View RelatedI have 2 routers the first is plugged into the telephone line and has a power-line adapter plugged into it the second router which is downstairs is just to extend the range,unfortunately I have a very poor connection (wireless) and internet often drops out. I want to reset the power-line adapter but but will this mean that the connection will be lost from the second router and it is just my computer that is wrong? My trouble is that I don't think the power-line adapter is working but it might be or... its just that the they both connect between each other wirelessly? Or do they both connect to each other wirelessly? both connections from each router are pretty poor. I have updated my wireless card as well. I am not resetting the power line adapter until I know the internet is going to be fine afterwards as my Dad needs it for his work

View 1 Replies View RelatedI have a brand new dir-655 of the B1 / 2.00NA version. It seems to keep a connection alive, but the wireless signal will suddenly and randomly disappear from all of my devices. I have reviewed this forum for hours and have made many changes to my settings, but nothing seems to keep the wireless signal from dropping.
Deleted the B mode, made sure the DNS entries were present, stick on one channel, etc. There are no other routers here and all of my phones operate on the 5 Ghz frequencies.
I never, not even once in three years, had this problem with the A version of the same router, but now it's a constant problem at least once a day. Nothing has changed by the router same brand and model but the newer hardware version.
The only remedy I have found is to reboot the router -- my devices will reconnect automatically once the router reboots, but there is no connection discovered once the connection drops regardless of how long the router sits doing its thing.
I've also notices that there are no wireless clients showing under status/wireless...they were there earlier today, but since the latest reboot, gone.
DLink 655 Fully Upgraded Firmware Multiple Laptops have the same issue, each has a different O/S from OSX to xp, vista and win 7. As soon as any laptop tries to download files, youtube, even web pages... There is nothing wrong with my wired connection. The thing is, each laptop gets disconnected then almost instantly reconnected. It is very annoying.The only thing I have found to fix it is turning off my wireless security completely. This is unacceptable! I am a computer scientist and in the security field. Ive tried WEP with both key sizes, WPA-Personal is what I originally was using before I started changed settings.
View 9 Replies View RelatedSo I have a DIR-655 and my internet connection drops every day. I have replaced the DIR-655 with a linksys just to try it and it works fine. This has happened with more than 1 of these 655''s. Also I have clients calling saying the wireless drops and it will not let them reconnect until I reboot the router. I have updated to the newest firmware with the same issues. I know its not bad cause I have more than 1 655 doing the same thing at a different location as well.
View 1 Replies View RelatedI am able to connect to my home network with a wireless connection, and the signal is strong at first, but then immediately drops as soon as I move the laptop more than a few feet from the router and then can't connect at all. I have not had this issue with two other laptops with the same settings. The adapter has been uninstalled, driver updated, tried different router and adapter settings, etc. with no luck. Is it possible there is a problem with the wireless antenna?

i have a wireless device and every 1 hours the connection drops and i must reboot the device
Have a MacBook and using Firefox. All lights on the router and modem are green. Does the same thing no matter what distance laptop is from router/modem. Seems to do it in 2-3 minute intervals.
View 1 Replies View RelatedI got my wife a new laptop in October, and it runs on windows 7, since the 25th of december she has been having connectivity issues with her wireless card. She had 2 bars on her signal strength, and I wanted to take the signal strenght out of the equation, so I got a N range booster to put in the room she is usually in, she now has a signal strength of 5 bars. However she still loses connection to the internet.
ISP is Bell Fibe 25 Router is the bell modem/router in one. My son's Laptop goes in that room, and has no issues. I have made sure the drivers are up to date on both the router/modem, and on the laptop itself. The only thing I cna think of is that it is the card itself that is faulty.
I had a WRT54G2 router and began having trouble with my PS3. It would connect for a few minutes then it would lose the internet connection. I thought maybe it was the router so I have the EA4500 now. The same problem is still happening. I connected all of my other wireless devices to the EA4500 with no problems. The PS3 connects and signs me in and then two or three minutes I'm disconnected. I called Sony and Cisco for assistance but in vain. The PS3 is showing my network has nearly 100% signal strength so that isn't a problem

HW Version: A3
Firmware: 1.35EA
One problem with DIR-655.
Drops wireless connection very often. On the taskbar in wireless network center (next to speaker and time) I can find info: Limited Access. Router doesnt drop internet connection but only wireless connection. Sometimes 3-4 times an hour. It's very annoying especially when you upload large files (for example 16-20MB) to your mailbox. It drops connection and we get Limited Access and you can try to upload again and again. Anotner example during VOIP conversations for example on skype it drops and disconnects skype.Firmware was never updated just router was bought with this firmware. We are located in China so its correct.When laptops are connected using LAN cable it works fine but its impossible to keep laptops connected using LAN cables all the time.The problem occurs only when we are connected by wireless.QOS is enabled, WISH is enabled.When QOS and WISH disabled it's same also drops connections on WIFI.
I got an E3200-RM (refurbished).
I did not do a MAC Address Clone, when I connected it I just called my ISP and they enabled it. Internet connection with all devices right there, no problem.
Problem started next day, every day I have to do a hard reset because when I wake up I have no connection with all devices (1 Ipad, 2 Iphones, 2 PCs, 1 Xbox 360, 1 PS3): My SSID is seen on the network but no device can connect to it.
I changed the Channels to manual as said on other threads, but didn't work.
In addition to that, when I try connecting my PC with the ethernet cable to the router -instead of wireless-, I have no internet connection on the PC and any other device that I try to reconnect to the router wirelessly can't connect anymore (have to do a hard reset again and unplug the ethernet cable).
the WRT54G worked perfectly for me...
Is it possible to establish the WDS-connection on 5GHz and connect Wireless-Clients on 2,4GHz with these Acces-Points?There are some threads concerning performance-issues in combination with WDS on 541 - any news on this with the actual software-release?

Galaxy Note phone (running ICS 4.0.4) can discover and connect to file shares on my desktop system without any problems.Asus Transformer Prime tablet (running JellyBean 4.1.1) can see the router on the local network, but can't see my desktop. Even if I manually type in the IP address it can't connect to itLikewise my old WinXP laptop can see the router but can't see or connect to any other devices.
I tried connecting the NetComm router with just Wifi configured to one of the ethernet ports on the X3000, so I've got two Wifi networks running in parallel. If I connect to this second WiFi network with any of the above devices then they can all discover and connect to my desktop system on the wired connection to the X3000.
I have 4 desktops cat5 to Dlink DIR 615 router. All work fine. Any wireless clients, laptop or netbooks, see the desktop computers for a while then disconnect somehow. All machines can see the Internet through the router at all times. The desktops disappear from the laptop/netbooks but the wireless machines can be seen from the desktop computers but clicking on them gets 'Access Denied' message after a wait.3 desktops = XP, 1 98SE. All laptop/netbooks = XP
