The IT Depart has, in my opinion, 'thrown their hands up' on this situation. They seem to believe it is my McAfee; don't know for sure but guessing. They of course know more than me in general about this subject matter but, at this point, I do not see how it could be the McAfee. I have tried turing off the firewall and disabling it altogether but neither action has worked. Is there a means by which I can 'open a case' or does it absolutely need to come from them? It may be worth mentioning that, until this past week, the issue I am experiencing was intermitment - I could connect sometimes but not others. Starting last week, however, I have not been able to connect at all other than during the evening when I returned from work where they had my laptop and were attempting to determine and correct the issue. I thought they had fixed it until I learned from them firsthand that no problem was found and, on the second day, I again could not connect.
