Comcast Atlanta Traceroute drop

Recommended Posts

Hello all New guy here ! So be forewarned I am kinda dumb at all of this.

I have been using the exact same setup here for years without many problems. About 6 days ago my connection started randomly stalling. Speed tests show anywhere from 0.2 - 2.1 in a matter of a minute or two. Traceroute drops after hop 13 - the test failing. Here is what Info I THINK you need to assist me if possible.

running Motorolo cable modem through Netgear RT311 Gateway throgh Netgear 8 port Switch. System is p3-133 1gig ram on XP SP2

Seems pretty consistant with the drop at the same IP every time.. I Also went here http://visualroute.visualware.com/ and got these results which give a little more info I can understand like where each trace is coming/going from/to  hope this helps.

Yea  I started having issues about a week back when they first started this maint BS. Now I have problems with stability.

Also after reading and searching every site I could find I Still cant figure out how to make myself Pingable with my rt311 router. I dont have 1/2 the menus they tell me to use.

I am stealth to all inquiries using Symantec Security Checker which is Good, but it dosn't allow me to run these tests.

Any Clues or advice is appreciated as always.

Thanks for all the time and efforts.

ok Finally got a confirmed answer through the techies at Comcast. Seems a firmware update with the new upgrades they have been doing to their system is NOT compatable with the older Toshiba and a few of the original RoafdRunner Modems.
