Do mention that you need to enable the security on the router.
I didn't talk to router tech support but, the router is resest and there was no firmware update right now.
Once the security is enabled then you can be sure that no one else is using your wireless network. The security for the router is on
This should make a lot of difference if the problem lies with the networking part, I mean the router and the security etc.
If still the problem persists then we need to check all the system's for any virus or spyware infection and probably would need to do a clean up job and adjust some settings to improve the performance of the system's. I will tell you how to do that in the next post. I think this is what I need to try at this point.
I am a former Dell technicall support specialist and all I want to say that this is a very common issue and very easy to fix. We just to follow a systematic approach to isolate the root cause.
Good Luck!!
