    If I may as this has nothing to do with Tomato? My daughter and her family just moved from Watertown, MA to West Newton, MA (Boston burbs and just a few miles apart). They have one of the Linksys N routers and their ISP is Comcast. They are using the same Comcast Arris modem they had in Watertown and their same router. Their download speeds aren't 20mbps but I was still getting mid teens. When I was there last week the network would drop a lot. I changed the router's channel to 11 and that really helped with the drops but even the hard wired desktop often will not "fined the server, try again" or what ever the error message says. Indeed though, wireless or hard wired when you hit the "Try Again" tab it will almost always render the site. A Comcast guy had to come back because billing didn't transfer the phone account or something and my daughter informed him about the drops and he said it was probably all the horse hair in the house! Well, even if that was the case, it would not account for the hard wired desktop. So finally I get to my question! We are going there next week again and I was wondering what tool(s) you would recommend that might help diagnose the problem and what should I be looking for? I did check their modem signals and the signal to noise ratio was in the mid 30s, downstream was 4 and upstream was mid 30s, which I thought was kind of low but I searched and apparently not completely abnormal. Thank You!

    Well, I am by no means a guru, but i'd suggest you test their equipment first. Plug a computer directly into the modem and see if the drops still occur. If that's the case, call the cable guys to fix the issue. If the drops only occur when the router is in the circuit, then it might have something to do with the router's presence, and then you can start troubleshooting from there.

    It sounds like the Comcast DNS is intermittent.

    Try changing to one of the open DNS servers such as 4.2.2.1, 4.2.2.2, 4.2.2.3, etc.

    Thank you and I believe that may have been it. Family reports it's been fine for almost a week and indeed no problems today. I suspect Comcast cleaned up the problem, perhaps there were other complaints in this location.
