My home network is set up with all Win7 PCs with router. The internet connection is ATT DSL. It worked very well.
Recently, there is a very loud noise in ATT voice landline when the modem is on. Using the landline will bring down the modem. Five ATT truck rolls, including telephone and DSL technicians, could not fix the problem. As a temporary solution, I call forwarded the landline to VOIP (Google Voice) to avoid the interruption of internet connection when I need to answer the inbound landline voice calls.
I am considering switching to cable internet. This will leave my ATT landline alone without the interference of DSL signal. Since I am running a home business, Stability of internet connection is the priority. I need to make sure the cable internet is stable before making the jump.
I need only one PC to do the test on cable internet for 3 months. I prefer other PCs stay on the DSL. However, this testing PC needs to be able to access other PCs in the home network. How to achieve this goal?
