Wireless dies?

[GreyGeek]

The suggestions I made in post #4 may work, since nothing else has been found to be of help.

As far as modprobe.conf not existing under /etc/modprobe.d/ you can create it. It is just a text file. In a console open kate.

kdesudo kate

add the line suggested, and save it as modprobe.conf.

Then reboot. (There are other ways but that is the easiest.)

[Jeremy_Ray]

And this same setup worked fine with 11.10 on the same hardware?

Yessir.

Did you upgrade or reinstall?

New install from CD.

Can you access the wireless if you boot from the Live CD of 12.04?

I'll give it a try.

Also, what OS and version is your laptop running (which you said works fine)?

Ubuntu 8.04 is on the hard drive currently in the laptop. Wireless works fine.

[SecretCode]

And this same setup worked fine with 11.10 on the same hardware? That leads me to suspect an issue with the version of the driver.

by the way, [ CODE ] tags are better than [ QUOTE ] tags - they preserve formatting and avoid smilies being substituted!

Code tags it is . . .

I meant you should find out the ip address (or DNS name) of your router and substitute it! For example if it was 192.168.0.1 you would type

ping 192.168.0.1 -c 1 -M do -s 1472

I'm not advanced enough with Linux to know better.

PING 192.168.2.4 (192.168.2.4) 1472(1500) bytes of data.
1480 bytes from 192.168.2.4: icmp_req=1 ttl=64 time=0.047 ms

--- 192.168.2.4 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.047/0.047/0.047/0.000 ms

I don't see anything odd in the iwlist output, except perhaps that "last beacon" time is much longer than what I see (never more than 32ms for me).

There's a problem somewhere, it's driving me up the wall.

Sounds like an error -

ping: unknown host ip.address

There's a potantially relevant bug on launchpad: https://bugs.launchpad.net/ubuntu/+s...ux/+bug/995467

I can't say this isn't the bug I have, but I didn't have a problem in 11.10.

[Jeremy_Ray]

Yes, I was using "card" rather loosely ... internally it must be wired into the USB system not PCI. And it ought to show up in lsusb.

Anyway, since it works some of the time this may be academic.

But one possibility occurs to me: since you found it originally only happening with Muon/apt, it could be related to large frames getting fragmented and the driver getting confused. Your MTU is 1500 (the default for Ethernet) but on some wireless networks I think it needs to be lower. If you know the IP address of your local gateway / router try this:

ping ip.address -c 1 -M do -s 1472

(1472 corresponds to a 1500 byte packet size, including 28 bytes of header)
If this gives an error (like "Frag needed and DF set") then your MTU needs to be set lower.

This is just a thought though.

It's not a card per se but an antenna a couple inches long, like a Bluetooth antenna. 11.10 handled it automagically.

OK, so it looks like a USB wireless card. That explains why it doesn't show up on lspci! But your lsusb listing also didn't show it, if I read correctly. That's odd.

Maybe it's disconnecting or something.

What is the output of

ifconfig wlan0

[Jeremy_Ray]

There's a Belkin antenna plugged into a USB port.

Well, that's odd. You don't seem to have a wireless adapter on either PCI or USB.

Maybe the adapter "disappears" after a while? Try

at different times, perhaps.

I was wrong earlier when I said the problem only showed up when using apt or Muon. It's showing up constantly in regular internet surfing now. I've got to disconnect and reconnect every few minutes.
