I have had Comcast high speed cable internet for a few years now and have not had any problems until recently. I can reach most websites but some will not load at all or will only partially load. For example, allaboutjazz.com does not load at all. I can reach forums.allaboutjazz.com but the images that point to allaboutjazz.com do not load. Another example is opendns.com. The text loads but the images do not. I have tried different browsers (IE, Firefox and Opera) and all 3 computers on my home network but the problem is the same. I ran tracert on both sites and it works fine. I'm stumped. Any help would be appreciated. Thanks for taking the time to answer questions.
ANSWER: What are the results if you ping the two different sites ? If the results are different (one pinging and the other is not - you could try using a different DNS server such as OpenDNS)
What firewall are you running ? Are there any filters / exceptions defined on it ?
---------- FOLLOW-UP ----------
QUESTION: Thanks for the reply. Both sites ping fine. I'm running Comodo firewall v3 with no filters or exceptions defined.
ANSWER: What is the situation when you put down (turn off) Comodo firewall ?
---------- FOLLOW-UP ----------
QUESTION: I turned off the firewall completely and there was no difference. I even tried resetting my Linksys WCG200-CC gateway to the default settings and that didn't help either.
Answer Have you tried changing your DNS settings ?
Try 208.67.222.222 and 208.67.220.220 (nameservers of OpenDNS) as the preferred DNS resolvers in your system instead of the defaults presently used.
There is a tutorial on using OpenDNS at https://www.opendns.com/smb/start/
