    DNS problems with 2-wire 3801
    Edited by timserious on Sep 22, 2011 at 11:18:32 PM

    I recently have had to power cycle (unplug power cord, coax and ethernet cables) and reset (via settings->diagnostic->reset on the RG) due to no internet connection. It eventually connects normally after 10 minutes, the windows network diags report the problem with the DNS portion of the RG.  This is happening whenever I boot or restart any of my PC's (vista and win 7), I have tried switching from wired to wireless (just to do a little troubleshooting) but it is the same, UVRT shows 4 corrected blocks and 31 DSL unavail secs since reset 14 h14 m ago. RG's LAN->statistics show only 1 error packet & 1680 discards xmit'd and 7 discards rec'd.

    Any help will be appreciated, I contacted support, they referred me to ConnectTech; I was promised a replacement RG on 8/26 but someone at AT&T cancelled the order.

    Try changing the DNS server in your computers to google - 8.8.8.8.

    Might you actually mean DHCP (not DNS)?

    Do you have any other SOHO routers on the net? If so, verify that DHCP is disabled on everything except the RG .

    No it is DNS not DHCP and this is the only router.

    Have you checked the stats on each of your computer's network connections? The reported dns server listed in those stats should be the address of the RG. If not, check your network connection config on each computer. They should be set to automatic for IP address and DNS servers.

    Thanks Computer-Joe, yes all of the settings are correct I have been connecting to this RG on all systems except my main system (I built it last month 8/4/2011) since it was installed 2/12/2011. This problem just developed a few days ago.

     

    I have performed major maintenance and performance enhancements as well as disabling services and startup progs that are not essential on all systems over the last two days, using Advanced SystemCare Pro, Smart Defrag, and a few other registry (cleaning and defrag) tools as well as manually doing what is needed and as of this AM things seem to be back to normal i.e., slow internet connectivity and downloads. So I cannot put my finger on what was causing the problems but for now this particular issue is resolved.

     

    Thanks again for the suggestions.

    Unfortunately, this now appears to be an intermittent problem as I lost connection for over 20 minutes today (9-25-2011), the windows network diagnostics again says "The DNS server isn't responding".

    Or try OpenDNS

     

              208.67.222.222

              208.67.220.220

    Very helpful Computer-Joe, I am currently rebuilding (my primary system, takes approx 4 days to rebuild completely) from format to re-installation of everything so I will try your suggestions, since it is an intermittent problem only time will tell, but I will keep you posted. I will however configure some of the other systems to test these, thanks again.

    @aviewer, I changed the DNS server settings on my systems to use the Google servers ip addresses 8.8.8.8  and 8.8.4.4, it seems to have resolved the problems, thank you!

    timserious - Glad it worked for you. I also like Google Chrome for a browser - very fast.

    In the past few days, I was having a DNS lookup problem, in the Indianapolis area. First the browser would hang with a "waiting for ..." messages, then the "can't find server" page would eventually show. Firefox was almost totally crippled, while Chrome and IE had it happen occasionally.

     

    Being that the DNS Changer malware is in the news, I checked again for that. And again for any malware or virus. Nothing bad found.

     

    So, I switched network settings to use OpenDNS. That completely solved the problem, at least for that particular Win7 PC. I don't have any other Windows PCs to check, and the two macs I have never had any problems. I don't know what caused the problem, but switching to a different DNS server fixed it.
