View Full Version : [ubuntu] Wireless problems

I decided to take the plunge yesterday with ubuntu. I had an old HD that I wiped and installed in my work PC. I kept my windows installation on the main drive and used the smaller drive for ubuntu. Installation went reasonably well. I do have connection problems though.

The problem is that Ubuntu doesn't seem to see the USB wireless adapter as it's not listed with the other hardware. It does see the memory card reader that I have though. The adapter I am using is an Edup ED-1296. It works well on Win XP and Win 2000 but not Ubuntu. Oddly I tried unplugging it and a window opened saying that the wireless network was disconnected.

I've tried finding a solution through google but nothing comes up. Does anyone know of a solution to this problem?

you need to update your drivers first. SYSTEM>ADMINISTRATION>HARDWARE DRIVERS

make sure you are connected to the web to update through a LAN cable in your case. Otherwise you will not find any drivers.

also try entering this into the terminal and posting the results on this thread


ifconfig


iwconfig

That is going to be next to impossible to do. My work pc is in my shop and the modem is in the house and ne'er the 2 shall meet. Is there another way?

yes but I do not know exactly how to do it. You need to find out what wireless card you have (the codes above can help you find out) then on another computer find the drivers DL them to a portable media then install them in the correct location on your shop machine. There is a special way to do this that I have no idea how to but some searching on this forum will post several examples as to how to do it right.

you might try this also, since you are using a usb adapter, make sure you have full rights over all usb devices.

System/Administration/Users and Groups
click on you user-name
click on Unlock
Properties button/User Privileges
check off every category

Even if that doesn't actually fix your problem, it should be done anyways.

If you go to the terminal (Applications>>Accessories>>Terminal ( in Ubuntu)) and type lsusb (that is LSUSB in lowercase) and either decode or copy/paste the output back here it should give the part number for your adapter and the code xxxx:xxxx

Here's the results from running the ifconfig and the iwconfig code, took me awhile since I had to install the printer and then print and scan the text

the output says "mode-managed" so I believe you have the correct driver installed whatever you usb dongle is. It also says that "power management is on so do you have a switch or key combination that enables wireless? Is it turned on in the bios? In the terminal do a

sudo iwlist scan

it requires your password which will not be echoed to you, just hit enter. You should see all the wireless A/P's around you and if they are encrypted or not. If you see this your wireless is working and just needs to be associated with your AP (the easy part).

You could try:

sudo iwconfig wlan0 essid your network's name
sudo iwconfig wlan0 key your wireless password, in hex
sudo dhclient


// I have two computers. On one, I use network manager. On the other, I had constant issues with network manager, so I uninstalled it, and use the above procedure to connect.

I've checked out that thread but honestly most of this is beyond me, I'm getting a headache just reading these instructions let alone trying to follow them. Perhaps Ubuntu is not for me, to bad because I like the rest of it
