Cisco :: AP1131AG Giving Connection Drops Randomly

Jan 10, 2011

We have a site running 2 1131AG access points on different floors with the same SSID.There have been issues with connections dropping over the last 2-3 months to some newer laptops and iphones that have been introduced to the network. It is almost totally intermittent and after updating the IOS and laptop drivers where possible, there is a still a problem that wont go away.I have some example logging from both AP's when this happens (apologies for the date/time differences, however the events are all sequential)

DIR-655 Randomly Drops Its Connection?

Aug 20, 2012

My DIR-655 randomly drops its connection. All devices on the network behave as though the network is not available, then again sees the network, and reconnects (all devices being two laptops, three smartphones, and a PS3...same symptoms). My modem does not have any problems, and I have tried resetting the router, but it has not worked.

4-5 Connected To Router And Connection Drops Randomly

Jan 23, 2011

Here's the problem, there are 4-5 computers connected to their router's network through both wire and wireless. Some of the other computers are used to stream tv dramas and what not, and it really kills the connection and I am barely even able to open a simple webpage.

Internet Connection Drops To Really Low Speeds Randomly

Jul 18, 2012

I just got a our internet going through our phone modem instead of a separate modem, a new router, and some new rewiring because lighting hit near my house and blew out everything, but now on the computer I built my internet connection drops really low randomly and nothing loads. It happens at random times and for a random periods of time. I ran malwarebytes and super antispyware and nothing showed up. I connect wirelessly with a asus usb adapter.I also tried a different usb adapter that I just bought and no change, and I tried changing channels on the router.Also we have three other laptops in the house and none of them are having problems. It shows me connected with five bars and good signal it just drops to almost nothing speeds.

DLink 615 E1 - Wireless Connection Randomly Drops?

Nov 13, 2012

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.

Intel 82579V - Gigabit Ethernet Drops Connection Randomly

Oct 22, 2011

My new computer has a problem with the on-board gigabit ethernet it keeps dropping network connection every few minutes. Nothing has had any effect. It has been such an annoying problem, I really was hoping to find a fix for this sooner as I know other people have had similar issues. Does anyone have any other ideas because I would like to use the only ethernet connection sometime in the near future. Having to run of an WPN11 netgear usb adapter at the moment.

TP-Link 300Mbps Wireless :: TL-WR1043ND / Connection Drops Out Randomly

Jan 19, 2013

Region : Austria
Model : TL-WR1043ND
Hardware Version : V1
Firmware Version : 3.13.4 Build 110429 Rel.36959n
ISP : TPG

I've got a problem with the wireless dropping out randomly. It may take a week before it stops or a couple of hours. I originally thought my microwave oven was swamping the signal when we used it so I relocated the router much further away but this hasn't changed anything. I can still log in to the router from a computer on the wired ports and reboot the router. It also thinks the wireless is working but everything looses connection to it. We have 3 laptops and 4 phones that use the wireless and they all cannot connect when it goes down. This is only a new device - less than 6 months?

Linksys Wireless Router :: E2500 Randomly Drops Internet Connection

Dec 27, 2011

I have an E2500 with the latest firmware upgrade (1.0.03). My configuration is simple, I have a fixed IP from my ISP with fixed DNS servers. I have one computer connected via cable and one connected via wireless and a laptop that gets connected on occasion wirelessly as well. I also have an android phone that I sometimes have the networking turned on and sometimes not. That doesn't seem to be affecting the router either as I've lost connections under both circumstances. The only thing I have different is I clone the MAC address as the ISP has my IP linked to my old Linksys MAC.
 
The problem is I randomly lose connection to the internet, the home network is still up it's just the internet goes down. I could be on the computer or not, sometimes while browsing sometimes after I browse for a while sometimes before I get started. Fortunately its not happened during one of my online games but it has happened just after I log off the game. It usually happens a couple of times a day.

Linksys Wireless Router :: E2500 Drops Internet Connection Randomly?

Jan 6, 2012

my E2500 drops the internet connection randomly. I have no issues with wired or wireless access to the home network (sharing files, sharing printers etc...). To fix the problem I log into the router and do a soft reboot from the status page.
 
I posted this earlier and the only response I received was a cut and paste answer to make some changes to my wireless settings. Seriously doubting the relevance of the post I made the changes anyway and as expected nothing changed, the router still loses access to the internet without any warning. When I replied that I hadn't thought that that was the problem but that I HAD made the changes mentioned and as I expected it DIDN'T work I get no response.

HP Pavilion Elite HPE-580t / Internet Connection Randomly Drops In Short Spurts?

Oct 7, 2011

ISP: RCN Type: Cable Security: None, had Microsoft Security Essentials running but uninstalled that to see if it was causing an error. Basic Windows Firewall is enabled (although have tested without)

The problem I'm having is the internet on my HP Pavilion Elite HPE-580t PC will drop for these short 10-30 second bursts. After the drop it will automatically start working again. This happens with all programs I'm running on the computer. The odd thing is that it's in a way random. Sometimes I won't get these drops for 30 minutes but then I'll get them every couple minutes.

I've been trying to pinpoint the problem but haven't come up with anything. I tried plugging the computer directly into the cable modem and still had a problem (which I assume ruled out the router as a problem). It also would seem to rule out this being strictly a wireless issue. I removed antivirus (Microsoft Security Essentials) and have tweaked with turning off the firewall completely. I've tweaked the power saving settings to make sure the adapters are not turning off. Even went as far as blanking the hard drive and re-installing the factory settings.

It's worth noting that I have no problems with other devices online. I have a laptop (uses XP) that uses both wireless and a direct connection to the router without issues. An iPad and Xbox 360 has had no drops when in use. This issue only happens with the desktop. The only difference in this device is it uses Windows 7.It doesn't appear to be the ISP (unless there is something they would do to cause issues with Windows 7) and the issue happens regardless of the router being used or not. It doesn't appear to be the wireless card since it still had issues plugged in. So I feel like it has to be either some setting on Windows 7 or some other hardware issue (Motherboard?).

Wireless :: Wireless Network Drops Connection Randomly?

Jan 12, 2012

I've tried two different brands of wireless network adapter now: a Netgear and a Belkin. They've both had the same issue.I'm running Windows 7, and the network connection will just randomly drop out. If I unplug and plug in the adapter, the network will reappear and it will connect to the internet just fine, until the next time it drops out.

WUSB600N - Internet Randomly Drops And Reconnects?

Apr 25, 2011

My wireless internet has been acting a bit weird lately. I use a linksys Dual band wireless-N USB adaptor (WUSB600N) to connect to my router, a 2wire 1000sw. I am on windows 7. Recently, the internet has been dropping and reconnecting the connection weirdly; it is apparent in Portal 2 Co-op mode; it says the connection has been lost to the server, and then within 4 seconds, re-joins the server. During that time, the little network icon (the 4 bars in the task bar) says "Identifying."

Internet Drops Randomly When Using Procurve 2910

Aug 31, 2012

So we recently moved our Comcast demarc to our new server room which resulted in moving the SMC modem from our old server room where it directly connects to the firewall - to a new room where it connects to a 2910 switch, LACP to our L3 switch, LACP to another 2910, then to Sonicwall.

Since the move our internet has been dropping off randomly for about 2-5 minutes then it will come back online. This happens anywhere from 10 to 50 times a day. Sometimes it happens a half hour apart, sometimes it is 15 minutes apart, sometimes it will go 8 hours without issue.

The modem has been replaced, the Comcast line has been "tested."

The modem remains online when we lose internet connectivity - I can connect to it using a laptop on it's lan port and ping out to google.com while an computer connected beyond the switch and sonicwall cannot connect.

I have run a constant ping from a home comptuer to the modem as well as to our sonicwall (both static addresses) and they both seem to go offline when we lose internet connectivity.

Since the issue started, I moved the Sonicwall so that it connects directly to the 2910 that the modem connects to, put it in a vlan with the modem so they only talk to each other and it still results in the same intermittent disconnects. I checked all the port statistics on both ports as well as the event logs, and trunk links and find nothing abnormal.

I take the switch out entirely and plug the modem directly into the firewall like it was prior to the whole move. Works fine.

Traffic is not an issue and the switch in question also connects all my production servers and iSCSI SAN together without issue.

Cisco :: After Connecting VPN Giving Connection Timed Out Error?

Jul 24, 2011

I had been working on our client servers through Cisco VPN using internet datacard. But from past 3 weeks after logging into Cisco VPN using my username/password, when I try to connect to any of the servers, it is giving connection timed out error.

Whereas, my team members across other locations are able to connect to the servers using my VPN username/password.

I thought there might be some issue with my laptop or internet datacard. I got my laptop formatted, even tried out with fresh new laptops & new internet datacards, but the issue remains same.

I have tried using vpn_5.0.06.0160-k9 & vpnclient-5.0.05.0290-k9 to connect but issue did not get resolved.

Internet Is Giving Limited Connection Error

Apr 22, 2013

I am currently on Time Warner Cable 10 mbps packge, and am using their wireless DOCIS3 modem/router. It is connected in my bedroom to the main computer. That computer stays connected. However, throughout the rest of the house (we have a two story townhome) it will drop completely or give limited connection...constantly. Sometimes I can have my laptop next to me and it will go out or give limited connection. The connection speed never drops, it just goes completely to no connection. Not for sure what is going on, if its on my end or time warner. Has been doing this for quite some time, the cable company comes out and changes the modem, but that's it, couple days later, goes back to doing it again.

Dell :: XPS 15Z - Wired Connection Not Giving Internet Access

Jan 14, 2012

I have recently bought a new XPS 15Z Currently when I surf the internet I am unable to use the browsers ( IE9 or firefox ). I am able to use non-broswer related internet applications like STEAM, MSN or QQ with no issues in terms of speed or stability. But when I use my browsers to surf, I can have periodic moments when I cannot surf the internet, such as IE9 which says that I cannot connect to the internet due to some unknown error. But when I run diagnostics, it says that I do not have any errors.  My adapter for my wired is the Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20). I have already contacted my ISP provider who have worked for with all the troubleshooting methods they can over the phone, and I trust that they are doing their best. But now it seems to me that the problem lies in my computer hardware or software and not in my router.

Cisco Switching/Routing :: E4200 Not Giving Android Devices Connection

Jan 3, 2012

I just upgraded to the e4200 v2 and I seem to be having connection issues with my android phone and tablet. Both are 802.11n compatable but they seem to have issues staying connected. Just so everyone is up to speed, there are two connections made by android, a general one to the internet, and a second one to the google servers (for syncing e-mail and contacts and the like) When just connected to the internet, the wireless icons are gray, when connected to the google servers as well, the icons turn blue. It's the drop in connection to the google servers that I'm having an issue with. I currently have the router set in full auto for channel and frequency band, but I've also tried setting specific ones thinking maybe the change in channel or something was causing the disconnect. The disconnect will even happen when I'm sitting right next to the router. The phone is a Samsung Galaxy Nexus (Verizon LTE) running Android 4.0.3 and a Asus Transformer tablet (Wifi only) running android 3.2.1.

Cisco Switching/Routing :: Nexus 5596 Giving Error In Connection

Aug 28, 2012

I have 2 datacenters running same equipement (two Nexu 5596 with FEX).I just took a look at the log just to see if everything is ok and I saw that I have the same error message (a lot of times) at both location :
 
%SYSMGR-FEX100-5-HEARTBEAT_LOSS: Service "satctrl" heartbeat loss 2 ,max 7,I though it was a problem with my peerklink-keepalive connection but I see the word FEX ....so i'm not sure...
 
Note that at both locations, my Nexus are connected back to back through the management port using transceivers. So it's a copper cable from the first nexus,  going into a transceiver, going to another transceiver in fiber and then back to copper to the other nexus.

Cisco Wireless :: AP1131AG Now Joining WLC?

Apr 17, 2013

I had problems joining a 1131AG AP to a "new" 5508 WLC with 7.4.100.0 running. This AP has been connected to a, for me unknown controller for years. Now the customer wants to move this AP to a newer 5508 controller with 7.4.100.0 We [URL] could not get this AP to the controller connected. Now I have this AP on my desk. I have a 5508 (7.4.100.0) as well. I connected the AP to the same network as the WLC Management -> AP did not connect, tried to download the "new" IOS but didn't seem to work, same as already in the old tread. So I tried to login to the AP, but it seemed to have a for me unknown Account / Password.
 
-> I did a reset of the AP by pressing the mode button (about 2-3 sec.) during Power on (not connected to the network). Now I could log on to the AP. I deleted six crashinfos and connected the AP back to the network.
 
Now the AP joined the controller.
 
Does a "unknown" Password prevent the AP to join to a other WLC?
 
The AP hat 15740928 bytes total (6409728 bytes free) space on the Flash: was this enough for the new image? 15740928 bytes total (7798272 bytes free) after deleting the crashinfos
 
The customer has more AP's that has to join the new controller, would be nice that we don't have to reset all APs.

Cisco Wireless :: Bridging AIR-AP1131AG With TP-Link?

Aug 19, 2012

Today I want to build a wireless bridge using AIR-AP1131AG (running WLC) and TP-LINK wireless router. The result is failed. May I know AIR-AP1131AG is support bridging the wireless connection with other vendor's access point or not?
 
In the TP-Link I already match its SSID, Channel and put the mac-address of the AIR-AP1131AG. In the WLC I already see too TP-LINK mac-address is already become a client.

Cisco Wireless :: AIR-AP1131AG-E-K9 / Getting PPTP VPN Through Access Point?

Jan 6, 2010

my customer has a very basic LAN+WLAN configuration:
 
- 1 switch (not Cisco)
- 1 DSL router which is the default gateway (not Cisco)
- 2 Wi-Fi Access Points (Cisco AIR-AP1131AG-E-K9)
 
If he tries to establish a PPTP VPN when he is connected to the wired LAN, it works but when he tries the same from the wireless LAN it doesn't work. He says he'd tested it with Windows Firewall disabled. Is there any configuration command that can enable/disable PPTP VPN traffic pass through a Wi-Fi connection? I've never seen something like this and I use PPTP VPNs over a Wi-Fi connection every day without any particular configuration on the access point.
 
Here's the APs config:
 
hostname ...!enable secret ...!aaa new-model!!aaa authentication login default local!aaa session-id common!!dot11 syslog!dot11 ssid ...   authentication open    authentication key-management wpa version 2   guest-mode   infrastructure-ssid   wpa-psk ascii ...!power inline negotiation prestandard source!!!bridge irb!!interface Dot11Radio0 no ip address no ip route-cache !

Cisco Wireless :: Configuring Antenna Gain On AIR-AP1131AG-AK9 After WLC Join?

Dec 8, 2010

I am currently working on a project where I need to design a complete wireless solution for a huge building.  I performed the wireless rf survey by configuring the wap's to broadcast a SSID and walked around gathering rf coverage data.  When configuring the test WAP's i did not join them to a lan controller ( AIR-WLC4402-50-K9 ) but simply created a static ip and ssid to broadcast but modified the internal antenna gain to +128 to change the direction of the broadcast.  There are two other ap's already joined to the lan controller on a guest network (configured by another contractor) but when I go into the lan controller web gui I do not see anywhere that allows me to modify antenna gain on the individual WAPs.  Also, once the waps join the lan controller they dont seem to be accessible via web. How I can I modify gain per wap?

Cisco Wireless :: AP1131AG / AP1100 Series Clients Roaming?

Sep 20, 2012

my hardware set-up : 2x AP 1100 series, 2x AP1131AG (not connected to a Cisco Switch)...all with the latest Cisco iOS
 
What i want to do is connect these APs and broadcast the same SSID (e.g Aironet and NOT Aironet1,Aironet2..etc). Doing that, a user with a laptop can roam between these APs and won't have to re-enter the password of the SSID every time he changes AP. I would also like the encryption to be with a 128bit password key. From what i have read, i need a local authenticator to do what (Something called Local Radius Server).

Bell Connection Keeps Randomly Cutting Out?

Jun 29, 2011

A couple weeks ago every device on my wireless network started disconnecting from the internet in unison and seemingly at random and then reconnecting. The time between these disconnects varied anywhere between almost immediately after regaining a connection and three to four hours later. As things stand I have a SpeedStream 5200 modem running into a D-Link DIR-655 wireless router. I have had no problems with internet connectivity up until this point. During each disconnect, every device remains connected to the router. I've called Bell and they claim there is no issue with the modem. To test their theory, I bypassed the router altogether, and attempted to connect through an ethernet cable, but to no avail, as the now hardwired device continued to get disconnected. These failures seem to be occurring between noon and 10 p.m. and to be honest I'm amazed that one has not cut this post short.

Randomly Lost Internet Connection

Dec 6, 2012

I was trying to browse the internet earlier, and I randomly just lost my internet connection. My homepage loaded up just fine, but then I tried to go to another site. It was taking a while to load. After about a minute a page finally came up that said "Server not found" (I use firefox). I can't get on any websites now and I can't get internet on any of my wireless devices either. When I right clicked my network icon on the toolbar and clicked on diagnose and repair it said "There may be a problem with the DNS. Windows attempted to find the well known host www.microsoft.com using dns. The server responded that the name was unknown." I have Windows Vista. Now I have no idea what I could have done. I didn't do anything out of the normal, just tried to go to a website that I frequently visit with no problems and this happened. This is what I get when I type ipconfig/all in cmd prompt. [code]
