Random wireless death :(

m0rte · 9 May 2007 at 20:58

I'd really appreciate some suggestions for this problem i've been trying to sort for 2 days :/

Got a Linksys WAG200G router - 3 PCs connected to it via wires and 2 PCs plus a WRE54G Wireless Range Expander connected wirelessly.
WPA2 encryption, Access list enabled, DHCP enabled.

Its been running smoothly for ages but, a couple of days ago, for no apparent reason the wireless has decided to stop working, something about the wireless NICs not being assigned network addresses as shown here:

(sorry, forgot who the good image host was..)

The wired internet is working fine luckily (or I wouldnt be posting this!)
I've tried disabling all wireless security, resetting router to factory defaults and reapplying settings, manually assigning IPs but nothing has helped!
I have no idea what to do next or what might be the source of the problem :[

Any suggestions appreciated!

Got a friend with exactly the same problem... but haven't had a chance to look at it myself - she's only told me about it over the phone, as she lives in a different city... will be interested to see the outcome of this!

Update:

Its a weird one..
Friend seems to be having exactly the same problem and it started around the same time. She lives a mile or so away and uses the same exchange I think. Her connection works fine with a ethernet cable but the wireless is getting the same 'Limited or no connectivity' error.

Just wondering if an issue at the exchange might be able to caus a problem like this? The ISP is BT.

Your exchange has nothing to do with the Wireless dropping out.

Maybe you should reboot your router, and install newer firmware.

rebooted several times, newer firmware was one of the first things I did, tried 2 different routers aswell and same problem on both :/
Have made some progress today tho, laptop seems to be working ok now (not quite sure how..o_O) but the desktop and signal booster still wont fully connect.
More tinkering when I get home later.

How many other wireless networks do your neighbours have? Maybe you are now on the same "Channel Number" as one of them. This will have the effect of reducing your network power.

Download www.netstumbler.com and install the program. Scan your area and see what other networks are available. Look at the channel numbers in use, and try and move away from them.

Channels are from 1 to 11. 1,6,11 are best choices. Or pick a number as far away from the neighbours as possible (as there is some overlap in the specs...)
