Ubuntu wireless problem

Crispy_Ambulance

Hi

I'm fairly new to ubuntu and have been running 9.10 very happily. I foolishly upgraded to 10.04 when it was offered and now my wireless no longer works. I can connect via the ethernet cable, but my laptop doesn't appear to be able to see the router and the terminal is telling me there are no wireless extensions.

The router is a Thomson and it was all working fine until today. I've googled and googled and there appear to be lots of people with similar problems on the Ubuntu forums but the explanations and suggestions are just confusing me.

Are there any Ubuntu users on here who can talk me through fixing this? I am having one hell of a week and this just feels like the last straw.

Loads of knowledgeable Linux users here, one will, I'm sure be along to help in the morning.

Two rules with Linux :-

rule one - never update
rule two - never break rule one

I wish I'd just left well alone but I had no idea that upgrading would be such a problem.

I have Ubuntu on my desktop and Windows Vista on my laptop.

I have tried reinstalling 9.10 from the disk and by the looks of things, I now have 3 partitions - Windows XP, Ubuntu 9.10 and Ubuntu 10.04. I can connect to the internet via the wired connection on my desktop but my laptop can't see the wireless connection. The ethernet light on the router goes off when the desktop is switched off (and I'm so frazzled I can't remember if that is normai or not). My laptop can connect via a cable to the router.

So - how can I remove 10.04 (if that is the culprit), or is this actually a router or laptop problem?

Now I feel like a wally! It turned out to be a router problem and nothing to do with Ubuntu!

So, now I have a HD with 3 partitions - Windows XP, Ubuntu 10.04 and Ubuntu 9.10 - is there a painfree way to remove one of them, preferably the reinstalled 9.10 that I no longer need?

Yep, go to System -> Administration -> Partition Editor (might be labelled as GParted).

Then you can delete the one you don't need, and stretch the one you do.

Fair enough, I don't have a fresh Ubuntu anywhere to check!

You might only be able to run gParted from the Live CD anyway to stretch the 10.04 partition.
Otherwise your mounted drive will probably show with a padlock.
If Ubuntu 9.10 has made an entry on the grub menu then afterwards update it using command:-

sudo update-grub

You can't change mounted partitions.

@OP: Do you have /home on a separate partition? If yes then it's straight forward. Make a backup of your documents or even better /home/<your username>/ first. Boot from a LiveCD, delete the old partition and resize the other one. You need only 20GB for / and the rest for /home. If you still have the old entries in grub, just execute "sudo update-grub".

I have no idea if I have /home on a separate partition - how do I check? (sorry if this question makes me sound like a moron. I really am rather inexperienced with Ubuntu)
