Wifi Connected But No Internet !.

[tickmike]

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 !.

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.

Hi.

I did record these yesterday (Below) .

I do not have a Smartphone !. The landlady said others connect ok except one person last year.

Hi Ben, how do I stop them. ?

Hello,

 

Can you ping an ip on the net, say 8.8.8.8?

 

If you can, try adding these lines into /etc/resolv.conf

 

nameserver 192.168.1.1

nameserver 8.8.8.8

I could Not ping anything past the the Router, I'm at home now but will try your idea tomorrow .

 

Edit.. Re.."/etc/resolv.conf" It says do not edit this file it will be over ridden !. Is it ok to edit that file for a test ?.

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.

[tickmike]

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 ?

[Arthur]

Google's or OpenDNS' DNS servers would be better. I wouldn't bother with your ISPs.

 

[b]Google[/b]
8.8.8.8
8.8.4.4

[b]OpenDNS[/b]
208.67.222.222
208.67.220.220

[tickmike]

OK thanks I will try that .

Update.

 

AM... Tried all above but still no internet connection, I'm going to a different location next to try there.

Also tried running a Live CD 'PCLinuxOS 2012.02 KDE' just the same results.

I did ask the pub landlady if she would re-boot her router but did not want to do that because of the tills.

 

 

PM ... I went to a public library and to a friends house to test wifi on laptop both connected with no problems but still would not connect at the pub.

There's clearly a problem with the pub's wireless router, not your computer.

[cpjitservices]

Chances are depending on what system the pub uses it could have something like a Captive Portal setup or MAC filtering.... You could ask them to allow the MAC on the router and see if it connects then.

[Michael]

It does sound like some form of MAC address filtering like I mentioned earlier, but it still doesn't explain why other devices can connect.

 

I wonder if it's anything to do with the encryption type or the channel the router is broadcasting on. Channel 13 can be problematic for some devices in Europe, hence it's recommended to stick to 1, 6 or 11 normally.

 

Channel 13's there, as many WAPs or routers are manufactured far far away from here and because they're designed for different markets, we end up with a one router fits all approach.

[tickmike]

I'm not sure if the landlord has been trying to set up the router himself because they had a massive bill because one of there guests in the B&B downloaded a load of illegal stuff and the police have been involved !.

I will suggest they get a 'smoothwall box' so it can be locked down more.

[cpjitservices]

no need for a smoothwall box necessarily... pfsense will do captive portal for free and has much of the same features.

Yes I agree but with the money they have they can afford to get something ready made, i'm not getting involved.

Not that it helps with your problem or original question but you could copy and paste it into a text file, save the text file, attach the the text file and you shouldn't get any smileys that way

 

Also I would try and get it working at or on her uni wireless. If there are any issues then at least there will be an IT Department of some description and may just be a case of passing the mac address to them to allow the laptop on there system or something to that effect ??

 

Then at least you know it will work with the Uni wireless system and won't have to spend more time trying to get it to work on the pubs wireless system ?

Thanks for that, I had been in touch with the uni's IT manager when she was offered a place at that uni and with us going on a visit yesterday I wanted to get it all working before we went so I could do a live test. but it did not work out that way !(thanks to the problems with the pub).
