Hi there, I have a very STRANGE internet connectivity issue that I can't figure out.

On my home network my laptop is connected wirelessly to a router, the router is connected to a DSL modem, and the modem is connected to the internet. Now the problem is when I boot up the laptop and let it join the network, the modem drops internet connectivity and is unable to reconnect until the laptop is turned off again. When the laptop is not present on the network the modem can connect to the internet without any problems. This strange issue only started in the last few days, up until now the laptop could connect to my network without causing any problems.

The technical DETAILS are:

laptop: MSI CR610, win 7, about 6 months old
router: Netgear RangeMax WNR3500 v1
modem: Netgear Ethernet Modem DM111P


This problem has me PUZZLED as the laptop connects wirelessly to the router, not the modem. Yet the router seems to communicate normally with the laptop, while modem is completely inoperable. Would anyone have any suggestions? I thought possibly a windows 7 update had caused a conflict, but I searched the web and couldn't find anything useful or anyone with a similar problem


thanks for your time,
MikeNo, I don't not have a quick answer to your problem.
But a couple of recommendations.
1. Make sure you have a backup of your data.
2. Contact your ISP and see if they have an error log for your connection.
3. Check out your AV software, are you sure it is working?

Yes, I suspect you have some kind of rogue software that ANNOYS your modem.
No, I can not prove it. Just my funny hunch.
One of many references that support this idea.
