I am running Windows XP SP3. I am on comcast cable internet with a Asus RT-AC66R. All my devices including this PC are connected by wifi.
The PC is running very well, I use and have run ccleaner, JRT, adwcleaner. I have comodo firewall and the problem happens whether comodo and my antivirus are on or off, no change either way. I am having no other issues with this pc at the moment.
The only problem I am having is accessing a few websites on this one particular PC, I have no problems accessing secure websites either. What I am getting is error "website took too long to respond"
If I use one of my other devices on the network such as a laptop or tablet I have no problem accessing the website.
I have tried resetting router and modem. I have also tried flushing ip flush dns. I have even tried an alternate usb wifi adapter.
The problem comes and goes sometimes it will access the website without issue then a couple moments later it will give the error again.
Thanks in advance for any ideas!
