Wifi Connected But No Internet !. Anyone have problems connecting a Linux laptop to a public wifi.?
Trying to get my daughters laptop ready for uni next month I wanted to try to see if it would connect to a public wifi, I went down to our local pub and used there connection (wpa with key) with there permission.
Having first removed all the network adapter's in pcc > network manager, I set up a new connection in pcc, entered the key, it connected and gave me an ip address but said it was not connected to the internet !, I have tried this several times, tried a reboot, still no internet.
I could ping the router ok but could not ping anything else past that.
The landlady said her laptop is ok on the internet at the back of the bar .
I did try http://192.168.1.1 in a browser for access to there router but it was password protected.
I have had this sort of thing at home and have to go to the routers settings page and click 'connect' but I can not do that on a public wifi. !.
I can connect at home ok to our 'wifi access point'. Do you think this is a DNS problem ?.
I have two days to get it sorted before we go on a day visit to her uni .
Edit.. It's the same with the firewall on/off !.

5th August 2012, 09:19 PM #2 When you obtained an IP, did you run ipconfig /all equivalent, as this would display the IP, Gateway and DNS.
If you have one, you could also try connecting a Smartphone and see if this works.
It does sound like some form of security, possibly MAC address, but normally you wouldn't even get an IP.

Can you ping an ip on the net, say 188.8.131.52?
If you can, try adding these lines into /etc/resolv.conf

5th August 2012, 10:24 PM #10 TBH it sounds like the router has blocked outbound access from the IP you had for some reason? I see this occasioanlly on Watchguard Firewall/Wireless boxes. Normally a restart of the router fixes the issue but i doubt the issue is with the laptop if it will connect at home.

What if I try putting my ISP's (Eclipse ISP at home) DNS servers in on the wLan set up page and trying that tomorrow ?.
Will that work on another ISP ?
5th August 2012, 10:44 PM #12 Google's or OpenDNS' DNS servers would be better. I wouldn't bother with your ISPs.
