Cisco :: 4402 WLC Users Not Able To Move From One Area To Next Without Disconnection
Feb 9, 2012
4402 Software Version - 4.2.130.0
1242 IOS Version - 12.4(10b)JA4
First off let me start by saying I am quite green when it comes to this equipment, I managed to get this project up and running with the equipment manuals, tech notes, forums and a lot of google work.
This setup has been up and running now for around 4 years with little to no maintenance or monitoring, I have been getting a few reports of users not being able to move from one area to the next without getting disconnected from our wireless, all of our users (about 400 or so) are running on newer Lenovo laptops on Windows XP SP3.
I know this is extremely light in substance with regards to troubleshooting, but where would be a good starting point to begin with this issue?
We use one RADIUS server with Layer 2 WPA WPA2 AES security.

Our Guest access system seems to be having problems with DHCP. It seems to take a while to deliver an IP address making the client device show the "limited or no connectivity" message, which of course makes the users complain. On one occassion I have seen my own client eventually picking up an address even after the limited connectivity message appeared. On another I saw the debug showing "Dhcp request for autoconfig address", which I suspect is a symptom of the problem.
Our Anchor Controller is the DHCP server and is a 4402 running 7.0.98.0 - I've attached some DHCP packet debug.

need to know the OSPF best design. I have a customer currently running their OSPF only in two area. Area 0 is provider reside and area 1 reside 700 hundred over of router including HQ router and remote branch router connecting to metro-E 10Mbps networks. Is this design have any weakness? Area 1 about 800 hundred router reside in, the HQ model is cisco router 7200 and remote end is cisco router 1841.Let's say they want a solution, for 3G remote router connect back to the HQ using Lease line with a fixed IP. Using DMVPN and OSPF communicating back to HQ. What should we aware when designing and implementing for the OSPF best practice. They have 700 hundred over remote branch need to terminate back to their HQ. I read cisco recommend an area should not be more than 50 router and per-area no more than 28 area.

I just recently had comcast high-speed cable installed, and purchased a Linksys E2500 advanced dual-band N router to get myself going. I'm running an Asus G74s series laptop with windows 7 and everything runs great while I am the only one connected.That being said when another laptop connects (Toshiba satellite also windows 7) the internet stays stable. It isn't until we try and do something that the internet randomly disconnects for 2 or more seconds before re-connecting and putting us in a constant loop of idiotic disconnection.
A quick example would be using the Toshiba to connect to World of Warcraft, I on my Asus can surf the web just fine for about an hour before it disconnects. When I try connecting to a, or the game at the same time it'll allow play for about 7 mins before the net drops for a few seconds then re-connects. This happens frequently no matter the time of day.I have attempted re-setting everything. Everything is up to date including the router. I've attempted to release and renew my IP. However I get this :

I am not good at networking. My friend wanted me to set up his home network.because the modem is unable to supply a good wireless connection to the rest of the household when the door is closed, a second router was needed.I set both routers to run with DHCP as they have many devices that needs to connect to the router for internet. However, a few hours after setting it up, my friend's pc as well as all devices connected to the second router faced issues. The router's interface showed that it does not have connection to the internet. they are still facing this problem until now.

I have a scenario where multiple branches are connected to Head Office via DSL links. The branches are located in differenct exchanges, everyone once in a while ALL branches go down at the exact same time except 3 branches and those 3 branches don't have ATM interface on the router, rather they have external DSL modem, all other branches that face the disconnection (for couple of minutes) have either HWIC-1ADSL-M or HWIC-2SHDSL and the DSL line is directly plugged into the card. [code]
I tried so many solutions like adding "operating-mode auto" command under the subinterface, IOS upgrade, changed dynamic routing protocol from EIGRP to OSPF... Nothing worked, on the logs of the router it just shows "EIGRP neighbor down", at the time of the problem I can't ping any of the affected branches on their WAN ATM interface although it stays physically "up up".Could the problem be a missing command that I need to add under the subinterface? Something maybe related to clocking or timeout or..?Note that hte problem occurs randomly, every few days, sometimes every 10 days, and all branches with ATM interface go down at the exact same time.

Here is my internet setup:Blue Zoom ISP (Satellite) >>> Their Modem >>> Sony Viao Desktop >>> Linksys EA4500 Router,I have a metal garage with an apartment in it about 30 feet from the house. I cannot get any kind of wireless internet into the apartment because it is made of metal. I barely have cell phone signal.So, in order to get internet into the apartment I have a Ubiquiti Nano Bridge mounted about three feet off the ground right outside of the apartment which runs a CAT 5 Ethernet cable inside the apartment into a Linksys EA2500 Router.

Basically I started disconnecting when I logged onto Blacklight Retribution after a recent game patch, after a few days the problem stopped and I was able to play again (with no changes to my computer) a few days later another patch was added and the problem occurred again, at first I thought it was a Blacklight specific problem (as this was my only installed game) however i installed a few other games (Kabold Online, Perfect World, Forsaken World, TF2, MW2 and C9) and I got the same problem on each of these games. I haven't been able to log onto a single Online game for more than 5 minutes, normally I'm disconnected at login, HOWEVER, my internet works completely fine in for everything else, i can browse the web, download game clients etc with no problem whatsoever.(Forgot to add, When i disconnect my LAN Cable mysteriously Unpluggs itself (according to computer) and a disable/enable in network manager reconnects it)
- Checked to see if drivers were up to date (they were)
- Rolled back NIC Driver (and put it back when this didn't work)
- Checked device manager for any problems with my NIC, (working as normal apparently)
- Tried setting my NIC to 100mbps Full Duplex
- Setting my power options to not interfere with NIC
- Had a DHCP error in my event logs so i set my gaming machine to a static IP
- Turned of UnUP, Turned on DMZ
- Turned off "Green Ethernet"
- I had other Errors in the form of a service stopping my NIC
- Phoned ISP, Everything is OK there end but they sent out a new router, but problem still occurs
- Noticed that a service was sending a stop control to my NIC, looked on forums for fixes and applied several of them
- Reformatted computer with old XP (switched from windows 7), updated, installed latest drivers etc and still same problem except now I don't get anything in event viewer when the problem occurs.
The only thing i haven't tried is replacing my NIC, but considering the internet works completely fine for everything but Online games I'm unsure how this could be the problem.

I have been experiencing random disconnection from the internet completely out of the blue lately. Router has worked great for a long long time. Now it just drops connection and is down for about a minute and then I can reconnect or reload a webpage.I have my xbox live and PC wired with a laptop wireless. It drops everything at the same time everytime. I hardwired my xbox to the modem and gamed all day. I would assume this could eliminate the modem as an issue. There isnt any inconsistencies with the router's colour or lights to my knowledge either.
I put a new Ethernet cable from modem to router to try and I thought it fixed the problem but it lasted problem free for about 6 hours then it crashed.

im trying to move the config from an 3750 to 3750 PoE but without using the PoE options.I have allready download the config with tftp and upload it to the 3750 PoE. Now the new config is stored on the PoE switch but some of the old setting are still there. Not sure why, i think the config only overwrite the settings which are in the conf file and the setting which are not in the conf file but enabled on it will stay on the switch.After the upload of the config file I deleted all the config I do not need by hand.They are some settings i can't delete and I don't know why, this are the sittings:
1. each fastethernet port has this option: "no cdp enabled" this entry was no availble on the old switch, is the any possiblity to remove this entry?
2. the same for "no mls qos rewrite ip dscp"
3 and for this one "vlan internal allocation policy ascending"

I'm trying to move some configurations over to an ASA5510 and some of the commands are a bit different than I'm used to (worked on old pix before)
I've configured the following on the device:
Outside interface: 65.66.64.34/28
DMZ : 65.66.64.49/28
Inside : 10.2.3.3/26
===========================
The current firewall has the below configured on it (old Juniper)
10.2.3.0/24 gateway 10.2.3.15 **10.2.3.15 is the IP for 3750 switch on the inside LAN**
10.0.0.0/24 gateway 10.2.3.4 **10.12.175.4 internal vpn- will remove later but thats a different discussion**
0 0 gateway 65.66.64.33 **to internet
10.0.1.0 gateway 10.2.3.2 **10.2.3.2 represents mpls traffic
[code]...
The current set up for this network has an mpls router and a vpn concentrator as part of the network my aim currently is to replace the juniper with an asa5510 the changing of the vpn tunnels will be for a different time:
work station ===> switch (3750) DG to =====> MPLS (vendor owned and managed) ====> non mpls traffic ====> vpn concentrator ===>firewall ===> router
The above will need acls to go with the routes, which I should manage ok just want to make sure the routing is configured properly

My internet connection is definitely ok, i could surf the web etc, i can dl other things EXCEPT all online lectures from my uni's site. The download is stuck at a few kbs/sec and it wont move, no progress or anything but later on it automatically states that download is completed. And the file doesnt amount to its rightful size which is a few MB. I used to be able to dl without any problem, this occurred quite suddenly. It happen few months ago, I thought maybe to give it some time and it would be ok.ut Ive tried many times and I dont think it is anything with my uni's site because ive tried to dl the same file with another computer which is successful. I tried switching browers, reinstalling my browsers and turned off my firewall but they wont work.

Well I just built a new computer but I didn't buy a wireless card because I figured I could just use the one from my previous computer. The problem, however, is that I can't seem to find the wireless card at all. All I see is a sound card and a video card plugged in so how was I able to get wireless internet on the computer in the first place?
For what it's worth the motherboard is a M2N68-LA

I currently have the following set up in my basement: Modem to 8 port router which has cables going into a patch panel which in turn provides internet access at 8 wall outlets throughout the house. My data/video streaming needs are expanding and I have had additional wiring pulled to the new locations. I would like to know if I can bypass the patch panel and go from the Modem to a 24 port switch to individual wall plates throughout the house.
