Laptop performs really slow when running from wifi
 

Hi All

I am running ubuntu 7.10 on my laptop. It is a HP Compaq nc 6220. Here
are some hardware specs

- 512M (builtin) + 1G memory chip = 1.5 total ram
- Intel(R) Pentium(R) M processor 1.60GHz
- 02:04.0 Network controller: Intel Corporation PRO/Wireless 2200BG
Network Connection (rev 05)

In ubuntu 7.06 I had no issue with wifi.

But I notice my laptop slows down, mouse starts flickering, keyboard
to screen response very slow. It
happends *only* when I run my laptop for few hours or so on wifi.

The only way I fix it is by rebooting the laptop.

Is there a way to fix this issue

Since you mentioned running laptop few hours or so made your laptop crawl, I would suspect overheating problem. Linux kernel usually logs such incident in kernel dump message so maybe when your laptop starting to crawl, you need to open a terminal console and type:

dmesg

And look in last few lines at bottom of that log.

It does not make sense. Why would overheating be a problem *only* when
running thru wifi?

maybe when your laptop starting to crawl, you need to open a terminal
console and type:

Perhaps you could show us your laptop hardware configuration? You can copy and paste the result of following command*line :

sudo lshw

In case you do not have lshw application in your ubuntu, following command line would install it*from debian repository:

sudo apt-get install lshw

Did you notice anything conspicous from dmesg result last time I ask you? How about paste it here as well?

Laptop performs really slow when running from wifi
 

Anyone else have any suggestion as to why my laptop crawls after
running for a while on ONLY wifi?

Should I downgrade it to feisty fawn? I had no problem with wifi there.

What is the simple way to downgrade?

I have the same problem, I think.

Perhaps because I use wifi, my log file of certain networking events is
becoming too big in the RAM? Can anybody here throw some light on
this issue?

I would assume that since your mouse "flickers" and screen refresh is
slow that something is consuming a large amounts of cpu. Run 'top' or
'htop' in a terminal (or tty, ctrl-alt-f1, ctrl-alt-f7 to return to
Xorg). The offender should be at the top of the list.
