Wireless help needed( I don't wanna go back to Windows)!!

Horton663 · 02-15-2011, 11:45 PM

I am brand new to the world of Ubuntu 10.10. I have an acer revo 1600 that was running XP until this weekend, when it crashed. I have installed Ubuntu 10.10 on my machine, and cannot get it to find my Hiro H50191 (which runs on realtek drivers) wireless usb. I run strictly wireless, with no way to run an ethernet cable directly into the computer, unless i can somehow use my shared network off of an old Dell laptop running XP. Help?

if you can't install driver you can use pinguyOS that has drivers included.

Okay, Posted before about wireless trouble, tried some of the advice I recieved, to no avail. So after a week of beating my head against the wall, I went to a pro. After spending way to much money for this service, the man installed a wireless N card in my Acer Revo 1600, and this apparently worked because I can see by the browser history, that he tooled around a bit to test it. Also, it seemed to be detecting the signal from my Netgear WNDR3300 router,(unprotected, I'll add, because I've never minded if others tapped into my signal, more power to 'em).However, I am still not able to access the web myself. What else can I do. I have also tested another, older Netgear router and come up with the same results. $^$#&%$#&^ !!!

Horton663,

I would suggest trying the following.

1. make sure you have an IP address assigned to the network interface. Run "ifconfig" to see the interface and IP addresses.
2. run "netstat -rn" to see you have a gateway setup. There should be a default route pointing to the router.
3. trying pinging the router to make sure you have connectivity "ping <router IP address>"

Post the output of those commands here if you still have problems.

You mentioned that this is an Acer computer. Did it come with Linux? If so, it's probably a dumbed-down distro called "Linpus". You should probably get rid of it and install something like Ubuntu or Mint.

@Horton663: I've merged your two threads, since both contain details about the system configuration. Furthermore you mentioned the advice received in the first one, hence I consider your last post as an update. Finally I removed the word "Urgent" from the thread title, since it's considered rude for people spending their time voluntarily to help others. If you disagree, feel free to contact me by e-mail.

hi, i have an acer revo too:these commands are to help us to know what your system thinks is installed (not necessarily to get you connected).

Code:

lspci # will tell us the pci devices you have in your system.
lsusb # will tell us the usb devices you have in your system.
ifconfig # will tell us what network interface cards you have turned on in your system.
ifconfig -a # will tell us all the network interface cards you have in your system.
iwconfig # will tell us which of your network interface cards has wireless capability

now that we know that, this should get you connected:

Code:

sudo iwlist device scan # this will use the device interface (that from the above command, we found out has wireless capability) and scan for wireless routers that are accessible.
sudo iwconfig device essid "myssid" # assuming no security, use that device to connect to your router.
sudo dhclient # will attempt to get ip-address, subnet mask, dns server information automatically from your router assuming dhcp is turned on on your router.

also, please show us the contents of /etc/resolv.conf.

did you have problem with wireless driver? before this I also have same problem, but I have solve with install ndiswrapper in my ubuntu 10.04. With ndiswrapper, you can use windows driver to make sure your wireless device installed properly. You can install ndiswrapper from Ubuntu Software Centre in Applications. Then search ndiswrapper.

What you need in you need is .inf file in your wireless driver. Maybe you can find wireless driver for windows from acer website. Than after install ndiswrapper, you can open ndiswrapper software and select .inf file.
