Intermittent network connectivity after Netgear router crash

[Sumatra]

Desktop system was running fine prior to the Netgear router crashing (WGR614v8). Following the crash, absolutely no indicators lights remained on router.

Turned off the PC and unplugged the modem
Disconnected the system's network cable from the router
~ 15 seconds later plugged modem back in & plugged in system's network cable
After all lights were responding, restarted the PC.
Cleared temp internet files and cache

Attempted to access the home page on each of the system's 3 browsers: FF, IE8, & Chrome: access timed out on all 3
Retried all 3 and after several seconds (~30-45) the page would either launch or fail again

Contacted Time Warner/Roadrunner to initiate a chat. Speed tests were run (download & upload) and all fell within their optimal range for my level of service. As soon as I could connect to a site that I normally visit, the issue was considered "resolved."

Immediately launched another browser, and it timed out again ...this time with DNS related issues sited. Called TW again and a site visit was performed today. They upgraded the modem. Again the download/upload fell with the range of service but the tech indicated that something was definitely wrong -- either software or hardware related.


Later I updated the defs for malwarebytes and AV running scans offline. Both resulted in no issues. I want to rule out hardware before proceeding to a re-image at this point.

Additional actions:
Ipconfig /all etc...
Windows Network Diagnostics: reports no problems
Intel Diagnostics:

As a side note, my XP laptop can connect without any issues. Any help would be greatly appreciated.

Hmmm. well. that is almost fixed.. you are hard wired to router or wireless ?

 

[Sumatra]

hardwired

 

[Yard Dog]

Any chance you have another router or is that the only one ?

 

[Sumatra]

That is the only one and I'm preparing to head out of town for a longer w/e. My plans were to shop for a new one upon my return my next week. Question... what would happen if i disabled the DNS Client?

 

[Yard Dog]

You mean in the router interface page or in your services .

 

[Sumatra]

in services

When you type a web address into your web browser and press ENTER, you are sending a query to a DNS (Domain Name System) server. If the query is successful, the website you want opens; if not, you'll see an error message. A record of these successful and unsuccessful queries is stored in a temporary storage location on your computer called the DNS cache. DNS always checks the cache before querying any DNS server, and if a record is found that matches the query, DNS uses that record instead of querying the server. This makes queries faster and decreases network and Internet traffic. Internet Explorer has it's own DNS cache it manages, not including this one.
