Just spoke to the client's wife and she stated that since the router replacement that the internet has been consistent, but if she leaves the computer for a few minutes and comes back, then she has to restart the browser. She said it is a bit slow loading up the homepage on browser startup. This is on the Mac. Thus, I am beginning to think it is the internet connection/modem issue, as it is happening on two computers and the router is new.
I'm completely stumped. A quick overview of the problem:
A client has 2 computers, one PC and one Mac with DSL. He was having problems getting online. During these times, he would receive a page cannot be displayed message or just could not get online. During the outages, he was able to ping the router, but not the DSL's DNS servers.
If he unplugged the router and plugged it back in, the internet would work fine. Thus, I diagnosed the problem to most likely be with the router, since both computers has problems getting online (Thus, no network issues with the computers.) and all the lights on the modem were on.
He received a new router and everything has been working a lot better than before. He, however, is still experiencing a rather strange issue. Only sometimes, not all the time, when he first starts up Internet Explorer or when he has been away from the computer for an hour or so, he receives a page cannot be displayed error. It does not happen all the time, only occasionally. This also has happened on the Mac a time or two since replacing the router. After receiving the error, he can restart Internet Explorer and it works fine.
I am completely stumped. Any idea on how to fix this problem? I have had him change his start page and am considering having him switch to Firefox to see if he sees a change. Any other ideas? All help is appreciated!
