View Full Version : [ubuntu] Wireless router freezing after 11.10 upgrade

Upgraded this week, went well, except that now my router goes down about every minute whenever I enable wireless. When I disable wireless on that machine, the router comes back for the other computers on my network.

This pc was actually working fine for a day after I upgraded to 11.10, but then I did updates through "Update Manager", and the problem started. Settings look good under Network, but something is obviously wrong.

Possible hint- I have a strange prompt under the terminal; don't know if it's related:

xxxx@xxxx-N68SB-M2S-Invalid_Entry-Length-3-DMI-Entry-table-is-broken-Stop:-$

Thanks

Not sure if wireless issue and DMI table are related. I found out in Ubuntu documentation that the DMI table is a listing of system hardware, along with associated info about serial numbers, part numbers, and other info related to the specific pieces of hardware in your system. You can list the DMI table with the terminal command:

"dmidecode"

which lists out the table in full.

Here's my listing, no idea how to fix, or even if it's a problem (beyond having a stupid looking prompt). Note that the problem is the very last listing (Part Number: <BAD INDEX>):
