Ubuntu 8.10

Boffy · 04-22-2008, 01:15 PM

EDIT: I meant 8.04 not 8.10! Reports suggest this card now works fine with 8.10

Hey Guys,

I've just installed 8.04 and the internet is really slow (~24kbps norm~500kbps). I've tried a few fixes and they don't work (i.e. this one: http://ubuntuforums.org/showthread.php?t=616744)

I'm really struggling here and would like some help. Here are some key files:

ifconfig

strange, which network connection is slow? the wireless one or the wired one? Are you behind a router, proxy, firewall?

Boffy · 04-23-2008, 01:16 AM

I'm behind a belkin router. The wired connection works great, really fast.

It's the wireless that has the problem.

I have two boxes with the same hardware and both have the same problem on 7.10/8.10.

Windows has no such problem.

It's really quite irritating.

ctrlchaos · 04-27-2008, 12:52 AM

Installed Ubuntu 8.04 yesterday & got the same - frustrating - misery with the wireless.
Tried most of the hints on several boards, most of 'em say it's the IPv6, but nothing worked for me.

The data in the etc/resolv & ipconfig file have the correct DNS servers, yet it all goes granny style, utterly utterly slow

The network icon also states that the connection is limited to 1Mb/s, in reality I can only get 480kb/s at best. Mostly just 280kb/s.
I have a 10Mb/s line!!
Also the network quality doesn't get much higher then 50%, sometimes it goes up to 70%.
I get these results in WinXP using the Ralink tool

Code:

Tx 54Mbps Rx 48Mbps
Link Quality:Good 100% (bars = max)
Signal Strength:Good -39dBm (bars = max)
Noise Level: Normal -79dBm

It's this small error that'll make me go back to window$... :|

Boffy · 04-27-2008, 05:28 AM

Yep that sounds like my exact problem. It's something that needs attention or people will migrate back to windows. The ubuntu CEO himself even said the internet is the key to linux uptake.

ctrlchaos · 04-27-2008, 05:47 AM

Damn NDISWrapper to hell!

Tried it that way & after the reboot my wireless has gone up in smoke... Forced to XP again.

Don't feel like searching on how to get that running again. I'll use GParted, delete Ubuntu, reinstall it again & don't touch it before a solid solution is made.
It's beautiful weather outside, ain't spending this time behind a laptop

Boffy · 04-28-2008, 01:57 AM

Any ideas anyone?

mrcheeks · 04-30-2008, 05:39 PM

Well, I use ndiswrapper and I don't have any issues(Gentoo, pure Debian) - linksys card. Maybe a bad /etc/hosts file

To install your wireless card, download the native windows driver and install it with ndiswrapper(if the wireless card was already detected, disable the existing driver, blacklist it).

I never used the drivers detected by linux for wireless cards. I always disable the default driver(if the wireless card is recognized) and later I install the native windows driver. No issues at all...

Quote:

sudo iwconfig wlan0 rate 54M

got it all fixed for me

finally i can enjoy ubuntu to the max

Boffy · 06-07-2008, 11:23 AM

No luck here sadly. Still very slow

metallica1973 · 06-07-2008, 12:54 PM

I just installed ubuntu 8.10 and it too is very slow. I am having disconnect problems as well.

tirithen · 06-10-2008, 06:21 AM

I have had this problem with hardy before, and I did find a solution for it, now I have installed a lot of updates and gotten this problem again, when I test my internet speed I get this same problem again. Sadly I cannot seem to find the fix which made it work.

syg00 · 06-10-2008, 06:36 AM

Check the driver - on 3945 the driver is bloody awful - heaps of errors.
Look at ifconfig.

Boffy · 08-17-2008, 04:27 AM

Code:

sudo iwconfig wlan0 rate 54Mb/s

solves the problem

EDIT: You also need to install the RA2500 windows driver using ndiswrapper.

redfox22 · 11-03-2008, 09:32 PM

I have a TRENDnet wireless USB adapter for my desktop, and was getting the same, EXTREMELY slow wireless throughput on my 10mb line.

I used NDISWrapper and installed the Windows XP version of my driver from the CD. Rebooted, and now I have expected speeds.

Same thing worked when I tried it on my Belkin USB adapter.

Thanks for the tip!
