OK - I have stripped it all back down to the minimum. I have deinstalled the McAfee software. I have run the MCPR software provided by McAfee to make sure that it is COMPLETELY deinstalled.
I have then gone through the process of deinstalling the network card, removed it, reinstalled the latest drivers, put the network card back in and it is still doing the same blo*dy thing !!
Before I replaced the wireless card, it was all rebooting fine. As soon as I replaced the card, and completed the Netgear driver install, it all went pear-shaped again...
I have come to the conclusion that (and I have Googled a lot of Netgear forums and the like) that there would appear to be a LOT of complaints about duff Netgear WG311T cards and I think that this may actually be a hardware problem....
I have removed EVERY other possible bit of software and it was all OK. As soon as I reinstalled the Netgear wireless card, it all ground to a halt again.
I am going to write to Netgear and complain about the card and attempt to get a replacement card, or better still get a different make of card. I only went for the Netgear card as I have got a WG624 router which allegedly gives me a 108mps connection.. I wish !!
I think that we have explored every possible software avenue. Only other question that I have is :
Are there any of the sysinternals tools which may give me a clue as to what it is doing during its 2 minute pause. The procmon/procexp doesn't show any CPU being used, there is no disk activity... I don't know what the heck it is actually doing !!
Otherwise it's a question of writing to Netgear and complaining.. I have even tried moving it to a different PCI slot in case there was a problem with that, but that has made no difference. I am now despairing of the damned thing and wishing that I had just kept my old USB wireless connection, which although slower, actually worked !!
I apologise if I have wasted your time on this, but I really can't think of any avenue that we can explore now ??
Yours utterly and totally fed up
