I love this forum! I was having the same half way working problem and now my DNS tests are passing in the diagnostics page. Let us see if this equates to no more halfway working net. Thank You!

Let me just say ditto to what eloquator said.
Thanks to these new settings, I haven't had any major connection problems that couldn't have been fixed with a simple browser reboot.
Thank you again.

Just to add to this thread. I saw on another thread where TSTT apparently has another DNS server: 196.3.132.153.
Try it and see how it works out.

I switched my DNS settings today, and I must say I've noticed an improvement already...

BTW, don't be lazy, go to the site, they've got instructions on there...

sorry to double post, but anyone else using OpenDNS on the Paradyne?

Is it normal for DHCP to give out the modem's IP as the only DNS server as opposed to the manually specified OpenDNS IP's?



I have a Speedstream at home and it gives the two (208.*) IP's via DHCP.

Just want to put my mind to rest on the issue. Any constructive input would be greatly appreciated.

Yea thats normal for a NAT router. It gives the pc its address as dns server so the pc sends dns requests to the router and the router translates those requests to its dns servers which are either auto set or manually changed by you. there is no advantage of setting your dns server manually to any ip other than your router ip. So you could set the dsl router dns servers to anything you want and rest assured every pc on your dhcp lan will be using them by way of the router. It makes configuration changes easier if you have more than 1 pc because you don't have to change the settings on each pc. I hope that puts your mind to rest.

Hey guys (and gals), I did the same using the 192.3.132.153 as primary dns and the 208.67.222.222 as the alternate. Seems to work well. I saw one person saying still got some connection issues. Can spyware and viruses be the cause? Of course, I mean after making sure the wiring is ok.

I've also been experimenting with the DNS 190.58.152.103 . It seems to work well. I've just started trying it so I don't know how reliable it is. It seems to be the DNS of the cuscon server tstt uses.

I think that was me. The problems seem to be gone though.

Interestingly enough, my modem doesn't list 192.3.132.1 as the TSTT provided DNS server anymore. It just lists .153 and .4 (secondary) now.

Do they work well? I sometimes leave stuff to download overnight and the .153 used to drop with me.

the settings on the router at my office changed from the 132.1 & 132.4 to the .153 alone... it happened when the area was upgraded to adsl2, dont know if tstt added the .4 back but I just manually set it to the .153 & used the sec. as 208.67.222.222 (opendns)

Ok I was reading in another part of this forum, that everynight when the connection resets (as we only get a 24 hr lease, everyday) the connection may drop. The author says to make sure the settings are on VC/MUX which I already had but the authentication at PAP. I just set it so tommorrow night I will know if it works.

Renewing lease is seamless and does not drop the connection or disconnect. If the connection is dropped then there is a dhcp problem. Maybe a problem communicating between your modem and TSTT gateway. My lease is set to renew every hour and no connections get dropped. If you leave stuff downloading and it drops then it is probably something with the reliability of your connection. DNS only resolves the ip the first time you access a resource, after that it is cached and reused so it is unlikely that dns has caused your file to stop downloading unless the server decided to change IP for some reason during the middle of your download. If you refer to p2p connections then those could be a result of dns timeouts because you may be flooding your connection with too many UDP packets so legitimate dns packets get dropped. For p2p over adsl I would recommend you disable UDP connections altogether.
Good Luck.
