View Full Version : [ubuntu] What should I expect from WIFI?

September 22nd, 2008, 02:37 AM
I have never encountered 'wifi' so I really don't know what to expect! I am using Hardy and have no problems with my network or connections. When away from home I use a notebook and my mobile phone as a modem. I run the usual Networkmanager 0.6.6 and GnomePPP for the mobile.

I have been in 'wifi' areas but I guess I don't really know even what to do to access the facility. Do I need more software or is there a button to press in order to 'scan for wifi'. Perhaps it will just find me! My notebook is wifi enabled but it is intended for Vista and there is a light and button that has to do with 'wifi'but that is for Windows.

I have read that Networkmanager 0.7.0 promises to do all these things seamlessly. It may be part of the new Ubuntu release. Is there a way of getting it now?

We need to know your hardware specs specifically your wireless card.
Open a terminal and enter
lshw -C network paste the output of that command here.

You will probably find that any networks will be located by networkmanager and GnomePPP.

Usually when I enter an establishment with WIFI, the network manager shows me all of the bars and if there is a password for the service I just ask the staff.

McDonald's fast food restaurant has WIFI and it sends you to a website to sign with various hotspot vendors, AT&T included.

I have AT&T DSL at home, so I just use my regular AT&T user name and password.

I myself use a Broadcom (not by choice mind you) I also don't see all the wireless that windows usually does. I also only connect at only a portion of the available bandwidth. (ex. 5Mb/s out of a 50Mb/s...10 if i'm really lucky. even if i am next to source.) I suspect its a driver thing and hopefully it will be taken care of in Intrepid when released. At least Wired works perfectly.

Thanks for the replies and I see as the answer that Networkmanager should indicate the availability of a 'wifi' network.

I'll have to go to Starbucks for a coffee and a trial-out!

I have the same card you have. You should be able to see the wireless networks just fine when going to network manager. I was able to see them all but could only connect to open access points (wireless networks that don't require passwords). My home wireless uses WPA and I could never connect.

I followed these instructions and it's been working fine ever since:
