Those instructions for Ubuntu 9.04 should also work in Ubuntu 9.10 beta.

If that procedure does not help, I suggest TEMPORARILY disabling encryption and enabling SSID broadcasting your router, to see if that helps. If it does, it means you need to lower the encryption level.

You need to enter the right WPA2 password in NetworkManager before you can connect to your WPA2 protected access point.

Thank you ..
The wireless works with me now, But it appears to be resting in peace , I just get an average speed of 5Mbps(as showed in connection info) compared to 54Mbps on windows with the same position of everything around and no one else connected with the router. , pls any help on this .....

any one for this.....

On downloads it give full 216 KBps speed but on web surf it is too slow......

Pls any help...

54Mbps is a theoretical max, and Windows clients typically misinform accurate data about this to alleviate this very type of question. It's quite unlikely you'll see this rate for more than seconds or minutes.

Your Internet connection is considerable slower I'm betting since most broadband connections do not exceed 50, and the worldwide average is around 3. (based on loose stats I've gleaned from speedtest.net, certainly review for yourself and I take no ownership over these numbers as they are just loose values, mine is considerable better than 3 and woefully less than 50).

So if you're able to run tests, speedtest.net is a good site to do this on you can get a good idea what your 'rate' is at any particular time. Running these tests at numerous times and averaging it out should give you a good picture of what to expect at any moment.

However if you are happy with your rate as you last post seems to indicate, yet web browsing is slow this may indicate this is not related to your hardware. You may consider that; a) Firefox has stale cached data and is having difficulty updating this info and b) DNS is causing issues resolving addresses from your browser requests.

Clearing your browser cache is a simple operation, in Firefox options select Advanced -> network and click 'clear now' under 'offline storage'. If you are NOT using offline storage you may want to enable it, since it will improve your browsing experience for sites you visit regularly.

DNS is a bit more involved to troubleshoot. You could discuss this directly with your ISP to see if there are any unique issues with them, or even changing your DNS to something like 'OpenDNS' and see if this improves or resolves your issues.

If you are using a proxy, that too can have adverse affects with browsing performance.

To summarize,

1) lets check your speeds and get a decent average over time. Ensure this meets your expectations according to your hardware, if not lets address that with your hardware vendor since they will have the best suggestion, maybe firmware upgrade or the like.

2) check with your ISP regarding DNS issues and ensure that the DNS is resolving in a timely fashion. This isn't something I recommend for most people to deal with personally, and if your ISP does not take serious these concerns, switch to OpenDNS to see if there is any change. OpenDNS is typically very good, but alas not completely without issues themselves but I find they are more 'open' about issues than ISP's on average.

3) check your browser cache and ensure its enabled and clear it occasionally to ensure good performance.

Given your prior posts it does not sound like your network connection is inferior by any stretch.

After trying these out and generating some hard statistics, you may want to provide more data specifically outlining your issues should they continue.
