I Keep losing Connection when streaming Video

Hello:
I have a wireless home network set up (One computer connected wired, two connected
wireless, tivo connected wireless) It is a Linksys Router BEFW11S4 Version 4 and
a Westell DSL Modem (With Verizon as my provider).

My problem is that whenever I am on the wired computer and I am streaming content
over the Internet (Video, Audio) I lose my Internet connection. I then have to unplug
the power to the router, turn off the modem and then plug the router back in and
power up the modem. It happens each time I stream a file.

I am lost now when it comes to trying to fix this. I spoke with linksys tech support
and they did not seem to have any idea.

I was able to stream fine with for the longest time and then this problem happened.
Also note that I was streaming fine with all of the computers on the Network, so
I do not believe it is caused my adding any of them. I have not added anything to
this network in the past four months.

I appreciate any help that anyone can offer.

 

best thing to do, remove all network devices, all software/drivers, delete the network settings, reboot, rebuild the network, 1 device, one driver install at a time.

 

I just finished doing this and still have the problem. I have also tried having just one connection going (unplugging all of the other adapters, one at a time) and it still has the problem.

I have spoken to Linksys Tech Support, but they were clueless. They did want me to change the MTU setting. I probably changed it about 10 different times. Starting at 1472 I dropped it to 1400, 1300, .... as low as 576. The problem was still there. They finally admitted that they had no answer for me and wished me good luck!

If anyone has any idea I would appreciate it. I am hoping to watch some of the baseball games down the stretch on the mlb.tv web site but without a connection I can't do that

Thanks!
