Wireless working, but can't connect

[Raoc3]

Hi all,

I'm fairly new to the linux world. I need guidance on my wireless setup.

Wireless Adapter: Netgear WNA3100 (Broadcom BCM43231)
Wireless Router: Netgear WNR2000 v3

I've got my wireless adapter installed and functioning, in that I can see the list of all the wireless networks around me, including mine, but when I select my network, and enter my password, it will not connect. I've done this over and over. My password is correct. I'm posting this on a different computer, so I can't copy/paste my mintWifi result

wlan0 ESSID: off/any
Encryption key: off

If there is something else the is important from that report I can post that. Wireless is on (according to the network icon dropdown). All wireless networks are visible, but I can't connect.

As I'm typing this, I decided to try to connect to my phone's hotspot, and that works. So I can connect to other wireless networks. Other computers can connect to the wireless network I'm trying to connect to. But I can't connect the computer in question with the home wireless network.

Any ideas?

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd

Can other devices connect to the wifi connection that you can't ie an other laptop or phone?

It sounds like the wifi access point / router won't let you connect !

[Raoc3]

Yes, windows laptop and several other devices have had no trouble connecting to the router.

-Router and internet are working, other devices can connect.
-Wireless adapter is working, can connect to other hotspot.
-Wireless adapter (Netgear N300) cannot connect to wireless router (Netgear N300)

I can see the network, try to connect, enter password, it fails to connect and prompts for the password again. Yes I am entering the password correctly.

But I can't connect the computer in question with the home wireless network.

--and it can always be your particular firewall setup, ufw or gufw (Ubuntu's firewall: using IPTABLES)

--you could stop tour firewall as a test, and since you have the router device: I have to assume you have an ISP provided setup, so you can check the router manual/admin (web page, a default password is usually given for the customer), and see what is or isn't turned on/off..

http://tech.mobiletod.com/how-to-enable ... ntu-10-10/

Code: Select all

sudo ufw disable
--temporarily stop the Ubuntu firewall

OK, so your local connection don't route (your router), a dns or ip error
--your name and password are no doubt fine: do the normal network troubleshooting

All on a terminal

• ping 127.0.0.1
  --your own host (localhost), tells you tcp is functioning
  [8]ping the ip address given by ifconfig or netstat -rn
• Ping your router
  --tests your gateway to see if you can reach the router's IP address
  something will likely fail in the above steps, so I would look over general network troubleshooting for a LAN, there are many guides available on the internet, I will give you a couple..

--windows style version (ipconfig instead of Linux ifconfi), otherwise pretty much identical

Yes windows connects with windows drivers, so Linux can too, however it will probably need to use ndiswrapper setup..
http://forums.fedoraforum.org/showthread.php?t=264484

Post 5, is a more complete answer: you would use sudo instead of su..

--you may also need a later version of ndiswrapper

And, it would be a good idea to check the chipset, seeing if anything else pops up to you..
http://linux-wless.passys.nl/
--fromthat link, the ndiswrapper supported chipsets/includes your USB device..
http://sourceforge.net/apps/mediawiki/n ... ar_WNA3100

Info
Reported to work with custom compilation.
--meaning you would have to compile it against your kernel, therefore you either would need buildessential(s), a Ubuntu package that includes Linux headers (your kernel version) + source file etc..

ndiswrapper, Linux setup method(s)..

post 1, however you can get the source files from the usual places, eg sourceforge, instead of relying on a users link..

http://sourceforge.net/apps/trac/source ... cket/13876
--this is a repeat of a Ubuntu user post, with his/her data setup and ndiswrapper install..

Ndiswrapper information and troubleshooting, step-by-step will get you somewhere, but you will need patience or fast typing: just don't go gung-ho nerdy about it, and you should be OK..

--from step 3.4 onward, you can see it is the same or similar to the other links given (as to the methods)

They also have a more automatic link, some of which ?could work, but just know that the versions are not identical, and the last update on the file was 2008 (doesn't mean it won't work), just that you have to watch the monitor and follow any steps you want to try

And, possibly someone has already created a quickie guide for Mint on ndiswarpper and that usb wireless card which would of course simplify things..
