LAN Controller issues

My friend just purchased a KT4V motherboard and is having some troubles with the onboard NIC. When he connects to his DSL service, it will only connect at 10mb/s. We've tried setting the connection type to 100base t full duplex, or even half duplex, but it will not connect. It only wants to work at 10base t full or half. Is this a normal occurance? If so, we'll just disable it and buy a linksys NIC. But I'd prefer to use the one that is on there. Any suggestions?

If this is normal, then why doesn't it work at 100 speed on a 100 hub? even forcing it? always at 10. I think there needs to be a BIOS update or driver issue. I have it on a 10/100 auto sensing hub, and always picks 10, regardless of cable/DSL modem or not... What gives??

Wireless Lan Controller Issue

Hi All,
We have a Wireless Lan Controller 4402 with software version 4.0.155.5. On Friday we experience a problem where our clients wouldn't get redirected to the internal webpage for authentication. It would just come up with page not found. We know the page was working fine becasue we could manually type in the
https://1.1.1.1/login.html and the
page would come up and you could login successfully. The users who were already connected to the controller were not affected and continued to operate. We have 2 other WLC's at the same software revision and they were not affected so I don't think it has anything to to with software level. Its like the webserver in the wlc failed to work. We failed over the AP's to the 3rd WLC and rebooted WLC1. After the WLC1 restarted we failed one of the previous non-working AP's back to it and it works again.
I know "now" there is debug commands to run at the time when the WLC wasn't working, but unfortunately I didn't know at the time. The WLC is running again fine and I was wondering if anybody has seen this issue before.
Any ideas on a fix or reason would be greatly appreciated.
Thanks,

We are running WiSM 4.1.185.0 and we just had the similar problem with one controller. The other three controllers were fine when it happened. The exactly issue was the nslookup failed(timed out) from the client, so the web login page won't show when people lunch the browser. A reboot of the controller fixed the problem. We have been running Cisco LWAPP for more than a year (from 4.0.155.5 to 4.1.185.0) and it is the first time we see this problem. TAC is still investigating the cause.

MSI 890 GXM-G65 LAN Controller Issue

Hello, Forum!
I have had this motherboard for the past few years, loved it, and then the LAN controller suddenly decided to "stop working." What I mean by that is that when I boot up, Windows loads, and then I have no network connection. I have updated the Realtek drivers, flashed the latest BIOS, disabled/reenabled drivers, renewed IP address, statically assigned an IP address, flushed DNS, installed BC Edit. The *one* thing that "solves" the problem is hitting F8 upon bootup and selecting "Disable Microsoft Driver Signature Enforcement." I'll have network connection again after that, but then it goes away upon the next boot up, so I have to do this *every* time I want to use the computer. This gets kinda annoying, especially when I do leave it on during a download from Steam or something overnight, it needs to reboot for updates or part of the install process, then it boots back up and connection is lost, so download doesn't complete until the next day when I reboot it *again* and do the F8 routine. Because I have a beast-sized graphics card and an audio card, I have no room for a separate NIC card.
Computer specs:
The aforementioned mobo in the subject line
AMD Phenom II x6 1055T
12GB DDR3 RAM
NVIDIA 550Ti 1GB
ASUS Xonar DG sound
Antec 450w Earthwatts power supply
I have been trying to Google the problem and ask people who were formerly Microsoft tech support, but this has not help. Can anyone help?

I run Windows 7 x64. I have a desktop and a laptop, both of which have had reinstalls done on them in the past (long before the LAN issue on the desktop happened), both had problems with reinstalling because it wouldn't let me re-use my product key. I then had to buy all new copies of Windows (I *really* try to stay away from torrenting). This is not a hassle or expense that I wish to go through again unless I *know* it will fix the problem.
Three things that I neglected to mention that I've tried are:
- System Restore
- Set to Last Known Good Configuration
- Installing a USB wireless adapter - that doesn't work either without the whole F8 routine.

Issues after changing the AP Name on Wireless LAN Controller

I recently changed the AP Name of all the Wireless Access Points in my branch office (which are all associated to the branch office Wireless LAN Controller(s)). After that I noticed that all branch office employees are unable to connect to the employee SSID. The employee SSID uses web authentication and employees are authenticated using Head Office AD via Cisco ACS, both located at the Head Office.
There are other SSID's on the WLC which all work fine, but only employee SSID which uses AD authentication does not work. AD authenticaion is working fine because employee's in HO are successfully able to connect to the employee SSID at HO.
The branch office is connected to the HO via a tunnel link. We noticed that if we restart both the ASA at either ends of the tunnel. The employee SSID starts working again but only temporarily for a day or so... what could be the issue? Can renaming the AP's cause issues? How can I fix this problem?
Thanks in advance

KT6Delta onboard lan controller freezes machine!

KT6Delta onboard lan controller freezes machine after a recently purchase of new ram.
TwinMOS PC3200 TwiSTER DDR 512MB CL2
Chip = WLCSP, (DDR-PC400MHz)
Why i believe the ram purchase is the issue, you say?
Well you see this ram model is not on the supported list on the motherboard information page to msi. allthough the 256mb model is.
so i had to manually configure the DRAM timing so that my computer would run at fsb 166 and ram at 400mhz.
But lets get back on track. Everytime i copy over the network (large files that use top network speed) the machine either freezes or i might get away with a complete network connetcion loss. so i have tried to copy at different speeds and foudn out that 2 mbyte a sec is possible without the computer hanging.
i contacted http://www.broadcom.com support base and they did not know of any simmilar issues regarding the broadcom 57x integrated network hardware. But they did say that my ram might be the issue because the network card sends its DMA packets there.
and i quote:
"Response from Broadcom: I am afraid this is not a known issue to me. But if you are saying with the different RAM this problem was not seen, this point directly to the RAM you use on this system and the compatibility issue. The RAM could for sure cause this type of the problem since the network adapter DMAs packets into and from the system memory (RAM)."
So can anyone help me? i really want to be able to use my network hardware normally and not being forced to sell my current ram chip and buy a new one.
I can't remember all dram timings options but here are those i do remember.
CL = 2.5 (yes didn't work with 2)
Row precharge time = 5
Ras pulse width = 8
Ras to cas delay = 5

What are your temps? Freezing often happens when CPU usage makes it too hot. I believe there is a way to check CPU usage in XP...
CPU temp is around 45-52 depending on what im doing.
Quote
I have a hard time convincing myself that the symtom - the LAN - is the cause.
What do you mean? its the ram chip thats the cause for the network freeze (or at least that's where it all is pointing at).
Quote
What is your video card? ...Tell us your system while you are at it!
Here's a quick list i made on the fly.
ATI Radeon 9600PRO 128mb ram
Amd xp thoroughbred 2500+
512mb ddr ram twinmos twiser series
KT6 DELTA FISR2 or something
2*160 gb maxtor sata disks + 2*80 gb maxtor ide disks
yeah thats it.

How to replace the certificate of Cisco 2106 wireless LAN controller for CAPWAP ?

I have interested in CAPWAP feature and I download the open capwap project to make Access Controller (AC) and Wireless Terminal Point (WTP). I had built the AC which used PC and WTP which used Atheros AP. The CAPWAP feature work well when I enabled the CAPWAP that used my own AC and WTP. When I got the Cisco 2106 wireless LAN controller (Cisco WLC), I configured the Cisco WLC to instead my own AC but I got the authorize fail in Cisco WLC side. It seem the Cisco WLC could not recognize the CAPWAP message which sent form my own WTP. I think this issue just need to synchronize the certificate between Cisco WLC and WTP.So I need to replace the Cisco WLC's certificate manually. Does anyone know how to replace the certificate manually with Cisco WLC ?
Best Regards,
Alan

4404 wireless lan controller managment via wireless clients

I am having an issue managing a 4404 wireless lan controller via wireless clients.
I have checked the box "enable controller management to be accessible from wireless clients" under management. For some reason that does not seem to fix the problem (page cannot be displayed). I cannot ping the controller by IP but other devices on the same subnet respond. Everything else works fine.
I CAN manage the controller when plugged in a wired connection.
When I do a route print it is identical wireless or wired. The route simple points to my interface. If I modify the route on my computer to actually point to our gateway instead of the interface then everything works. But why should I have to do this only for my wireless connection and not my wired to manage this box?

Thanks for the info. I narrowed the problem down to an ARP issue.
In order for me to connect to the controller, I run a batch file that creates a static ARP entry on my laptop. I don't have to do this for any other device except the controller. Not sure what the underlying cause is, but that works as a workaround right now.

Wireless LAN Controller not broadcasting network to Access points

Good Day Team,
I am working with a 2100 series WLC controller and 1100 series access point.
I noticed that the wireless lan controller is working. Also the access point is working.
The issue is that there is no internet connection on the access point.
What could be the error?
Kindly advice

Try do diagnose your problem following this steps:
1) Connect to the wireless network
2) Check your IP address with "ifconfig"
3) Check if your gateway is set correctly with "route -n"
4) Try to ping your gateway. Is it working?
5) Try to ping an internet IP like google: "ping 74.125.234.115"
6) Try to resolve names with "nslookup www.google.com" for example.
7) Try to traceroute to an IP or name on internet. Check the result to see the last hop you reached.
8) If you passed all those tests, try this: "telnet www.google.com 80"
If everything works, but not the test #8, your problem could be related to some proxy configuration.

AIR-CAP3501I access point not joining the Cisco 2100 Wireless Lan controller.

Hello All,
I am installing a new LAP (AIR-CAP3501I ) through the wireless lan controller (AIR-WLC2112-K9) with software version 7.0. I have an external ADSL modem which will act as the DHCP server for the wireless clients and the LAP.
Please find my network setup as below:
The ISP ADSL modem , WLC and LAP are connected to a unmanaged POE switch. The LAP gets its power through the POE switch. When i connect the LAP and the WLC to the switch along with the ADSL modem, the LAPs are getting the ip address from the ADSL modem, however they are not joining the WLC for further process.
ADSL Modem ip address: 192.168.1.254
Management ip address on the LAP: 192.168.1.1 ( Assigned to port 1, untagged Vlan).
Ap Manager ip address: 192.168.1.1 ( Assigned to the same port i.e port1, Untagged Vlan).
The LAP is getting an IP address from the ADSL modem in the range of the DHCP scope.
I will paste the logs very soon.
Please let me know if i am doing anything wrong oe what will be the issue.
Thanks in advance,
Mohammed Ameen

LAN controller

Dear All ,
I have Cisco Wireless LAN controller AIR-CT5508-K9 ,I had created a Web Authentication page for Guest VLAN users ,its giving the error "ERR_CERT_DATE_INVALID" when the users trying to access web-auth Page .
Kindly support me for the issue.
Thanks.,

If you haven't installed a 3rd party certificate, your guest users will see a certificate error because the wlc uses a self signed certificate. If your on v7.2, I believe that's the code this feature was introduced a, you can disable https for web auth. This way you don't get a cert error.

Lost connection on lan controller 2106

hi,
I have problem with access point air-lap1242ag-a-k9 work with lan controller air-wlc2106-k9.
the connection works well during a time but soon it is lost during few minutes and soon it raises automatic, this process repeats the day throughout. I have seen that valor AP ID in the LAN controller changes when this happens.
thanks for the aid
Marcos.

Hi Marcos,
So are you saying that the AP disapears from the controller for a little while, then comes back?
Are the APs in the same subnet as the management/ AP manager interfaces? I would do a debug lwapp events enable and check how many broadcast sources you have in this subnet. It happens that when there are too many sources of broadcast, APs get disconnected; isolating the APs in another subnet/VLAN usually solves the issue.

TSeries LAN connection issues across fibre link

I have some LAN connection issues when getting dhcp or even assigning static ip to T61 laptop. Doesn't get dhcp ip settings dynamic and if given staitc, can't ping any system on network nor can systems ping it. DHCP is at main site and this laptop is at remote site. Link between sites is fibre. All other systems at remote site where is laptop get their DHCP settings as normal. If I bring laptop from remote site to main site and plug in cable it gets DHCP normal but not at remote site, it doesnt get it, so i know the LAN adapter is good. What is wrong?, what across WAN link it preventing it? seeing that all other systems at remote site get their settings well. Thanks in advance.
