Laptop won't connect to Air at uni

[dwright 25]

Hi,

 

I can connect to Air over my university's wifi with my iPod Touch, but my laptop running Windows 7 won't do it. I have tried using an SSH connection to see if that would circumvent any deliberate blocking, but that didn't work either.

 

The wifi in general behaves strangely with my laptop - it does not give me internet access until I troubleshoot it, when Windows asks to reconfigure DHCP settings. I don't know what that means, but could it be deliberately configuring Windows not to allow VPN connections, but this blocking fails with iOS?

 

If anyone knows a fix, please let me know.

Not sure if it's the case, but I had similiar problem and using the "Resolved hosts in .ovpn file" from "Advanced options" in "Config. Generator" solved my problem with connecting at Uni.

I noticed there was no response from the staff yet, so I'm copying in a log of it failing to connect:

Thanks for the response Laiquendi, but I already use resolved hosts.

Hello!

 

Please try to connect to different servers and ports. In particular, test port 53 UDP and 80 TCP.

 

Kind regards

[dwright 25]

Okay, I tried the proposed ports and 2018 alternate entry as well, but no luck. Here is another log of it failing:

Any other solutions?

Hello!

 

Something is blocking OpenVPN:

 

Mon Nov 11 11:59:27 2013 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)

 

Since you can connect with your iPod, it should not be a block from your university. For testing purposes, can you momentarily disable your firewall and try again?

 

Kind regards

[dwright 25]

Hi, I use Malwarebytes Pro and Windows Firewall. Disabled Windows Firewall and "website blocking" in Malwarebytes and it still didn't work.

 

Note: when I connect to the wifi, it requires administrator priviliges to enable DHCP. Could this be changing some setting that blocks it?

[dwright 25]

Sorry to be a pest, but I thought I'd post the log of it failing with Windows firewall and all Malwarebytes active protections (filesystem protection and wesite blocking) disabled. Any more suggestions?

Hello,

 

the problem:

 

Tue Nov 19 14:31:52 2013 UDPv4 link remote: [AF_INET]84.39.116.179:53
Tue Nov 19 14:31:52 2013 MANAGEMENT: >STATE:1384871512,WAIT,,,
Tue Nov 19 14:32:52 2013 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)

 

A possible explanation, assuming that nothing in your system is blocking OpenVPN UDP packets, is that your ISP (college) does it, or maybe hijacks packets to 53 UDP to its DNS servers (a shameful practice we detected on Vodafone). However, if the same configuration works with your iPod on the very same network, then it MUST be something in your system. Please try also connections to ports 80 TCP and 443 TCP.

 

Kind regards
