Ubuntu wifi issue

So, I have a wifi card in my ubuntu machine... this is nothing new. It's been in there for quite a while, and I've never had a problem using it... until recently.

Lately, my computer has been having a hard time resolving certain hostnames... subdomains especially.

Also, the card randomly loses signal and has to reconnect to my wifi router. I think this may be related to the massive clump of cables on my floor though, some disturbingly close to my antenna... (within a few inches)

well, DNS resolving is not something that the card itself does - so your wifi card has no control over that (aside from its involvement in the connection chain to the internet)

not sure what you want here... without any info I can't even begin to try and point you in the right direction, but you might want to check the router

the router could be part of the problem. Considering it can't read the linux boxes hostname... (it marks my computer as "unknownpc1"

It's not the router anyway... the router works fine for my windows computer.

But still, give me some info here. Computer specs would help, as would a lsmod, iwconfig, lspci, and lspci -n output (all run as root)

The hostname issue is easy - just run "find /etc -iname hostname" - then just edit whichever one is the configuration one (mine is /etc/conf.d/hostname) and in there it should look something like


Code:
 # Set to the hostname of this machine
HOSTNAME="kllrnohj"

AMD64 Athlon 3500 I do believe. 512mb RAM, and it's a Beltin (I think) wifi card.

Sorry, I edited my post before I realized you posted here

I would also like the output of iwconfig - and check out my edit for how to fix the hostname issue Smile

The output from iwconfig is already there.

I cut out the parts that related to the other ethernet devices, since they're not in use.

well, iwconfig is showing a really poor link quality, so I'd try moving around the antennae on your wifi card and on the router, see if you can't boost up that signal somehow - doesn't appear to be a driver issue
