What diagnostics...and exactly what do they reflect/state?
Did you check Event Viewer for possible errors that would provide clues?

Looking for any errors that reflect on network/Internet connectivity.
Good morning Hamluis! I used Network Diagnostics for Windows XP, which came up on the screen when Internet Explorer failed to go into a web site, as an option. I clicked the big button on the screen and it went into a diagnostic test as to any connectivity problems. I printed a log report, which appears quite comprehensive.
The major findings were stated as follows:
" Corrupted IP routing table and invalid ARP Cache. Cache was flushed. repaired gateway"
Sounds great, but didn't solve problem. Had problem a second time, ran diagnostics again and got report but somewhat different...I don't have it with me here so I can't quote it.
I am now at a different location however, and the laptop appears to be working fine.
I still suspect it has something to do with Cablevision. I have a different internet provider (comcast) where I am now.
I'll bet when I return to my office, I will have similar problems-- again problems were:
Not going into Google Chrome internet; very slow loading and then failing to get into website.
Internet explorer would go on internet but then freeze and fail to honor commands or go into websites.
What do you think? By the way, what is ARP? I understand the cache language but what does ARP stand for?
I am semi-literate as to computers, and understand what the diagnostics did, but what causes this problem?
