PS3 serviio and internet

For the past couple months when my daughter watches movies stored on my PC it slows my internet to a crawl. I can't figure out what the problem is. I can reproduce this problem at will. I am using the ps3 over wireless. It connects to my modem which is a actionetc dual band wireless modem. Any thoughts would be a big help. Thanks

Shouldn't happen....
Is your PC also connected to the modem wirelessly? If so, try connecting it via cable, or putting it on the other wireless band (ie. put PS3 on 2.4G band and PC on 5G band).

My setup is as fallows.

PC Is wired to my modem.
PS3 is wireless
I don't know why this is happening. Have dynamic IP address. So as to not have a ip conflict. Other than that there's not much more I can think of trying

It is weird. Some things to look at when troubleshooting:

Is your daughter using online streams as these do use internet bandwidth? If its only local sources (ie. movies stored on your PC) then the internet isn't used.

It may not be that the internet access is being directly affected, but rather that it is swamping your access bandwidth (ie. between your PC and the router - hard to imagine this is the case ) or swamping your CPU on the PC, or swamping the router. Either case may make it appear that its internet related when its not. While streaming check:

• Firstly make sure the PS3 profile is assigned to the device in Serviio Console, Status tab;
• Check your Resource usage on the server (the PC Serviio is on). If a Windows user run Task Manager, and press Resource Monitor. Look at the your CPU, Memory, Hard Disk and Network. CPU should below 80%.
• Log in to your router and see if that shows anything about usage (not familiar with the Actiontec so can't help). Try turning firewall/SPI off and seeing if that helps.
• Copy a file between two PCs on your LAN and see if that is affected - if it slows to a crawl it would confirm my thinking that its not internet related, but LAN or server related.
• If you have 3 PC's do a file copy between the other 2 (if this slows to a crawl, its LAN and not server).

If this doesn't shed any light, try a detailed log from Serviio and see if that shows anything abnormal. Perhaps try disconnecting from your internet while streaming (and seeing if anything errors) and then reconnecting? Also, if your router can monitor traffic, see what that is stating is using the service?
