Hi,

 

Just began using Air about 24 hours ago. Experimenting with different ports. I have 2 questions.

 

I'm unable to connect using UDP/53. Getting, "TLS Error: TLS key negotiation failed".

 

1) Any idea what this is about?

 

2) What firewall are people using on Windows 7 that doesn't degrade the DL speed so much?

 

The reason I'm posting here is because my speed loss was a bit more than some of the others posted here:


 

UDP/2018 then disabled the freakin' FW helped.

 

In the event someone is experiencing similar issues (with Verizon) I've posted some of the results using a variety of 

 

ports.

Looking like UL speed loss is negligible using UDP 2018.

 

Read a few posts that there could be latency issues due to Firewall.

 

Shutdown Kaspersky processes the DL results improved:

Sorry for the rather lengthy post.

 

Thanks for your service!

Hello!

 

1) This is typically caused by ISPs which hijack packets to port 53 UDP to their own DNS servers (for example Vodafone Italia).

 

2) As far as we can see, most firewalls do not cause any performance hit, provided they are not configured to inspect packets or to log excessively. Packet inspection of encrypted packets can cause heavy system load (and it's not useful, because the packets are encrypted). Can you please tell us which firewall you disabled to have better performance?

 

Kind regards

Thank you for the prompt response. I am using Kaspersky Internet Security 2013 v-13.0.1.4190 (h)
 
Apparently I was mistaken in my diagnosis. I had varying results this morning w/ the FW on and off.
