WIFI was working now can't connect.
I have disconnected and reconnected nothing happened. I have looked at setings. SSID set, don't know much about the rest. MTU: Automatic.IPv4: automatic. Wireless security WPA is set. What else do I need?
My WiFi adapter is a Linksys compact wireless G usb. my system is Ubuntu 12.04. I am writing this on my laptop, for some reason, I am unable to show the results because when I try to copy the results, I am unable to copy them to my finger drive. |
Hello Millington,
I see you're new around here so welcome aboard! Your question doesn't give us much to go on. On my system (Currently Ubuntu 13.10) I can use dmesg to to see whats going on when I disconnect/re-connect to wifi. This may give us some clue as to what is going on for you. Disconnect from WiFi then open up a terminal and use the foillowing command: Code:
you@your_host:~$ dmesg | tail -n20 Now attempt to re-connect to WiFi, give it 30seconds maybe then run the command again: Code:
you@your_host:~$ dmesg | tail -n20 Best regards, Soldersplash. |
My WiFi adapter is a Linksys compact wireless G usb. my system is Ubuntu 12.04. I am writing this on my laptop, for some reason, I am unable to show the results because when I try to copy the results, I am unable to copy them to my finger drive for transfer to laptop.I cold started my router and that didn't work. I am going to reload Ubuntu and start over from scratch. It worked when I first booted the system.
Thanks for your help. |
Millington,
is your 'finger drive' a usb stick/pendrive/removable drive? Is it formated to fat, or some other file system or broke? Or are you copying incorrectly? If wifi worked first time round after rebooting a new install it should continue to work but strengh of signal can be an issue. From the signal icon you can click to see available 'networks' does yours show up? Alternativly show the output of '/sbin/iwconfig' from a terminal no quotes. Fred |
There's basically 3 things that make up a network connection. The device driver and configuration. The routing. And the firewall. Any of the three can disable your network.
# iptables-save # route -n $ netstat -r # ifconfig # iwconfig You can pipe the output to files. 2>&1 redirects STDERR to STDOUT. Pipe "|" plus tee sends it to a file while letting you see the output. So: # route -n 2>&1 | tee logfile.txt or redirect it to a file and not see the output. # route -n 2>&1 > logfile.txt |
Millington,
When you are logged into a command terminal in Ubuntu and have your memory stick plugged in, try the following commands. Quote:
