I am intermittently losing my internet connection. It is mostly my wireless connection, but I sometimes find my wired connection gone too. Comcast has done their thing as far as refreshing the modem. I use Airport Extremes in bridge mode to provide Wi-Fi to my house. I will run Speedtest on my iPhone or iPad, and I see a network connection issue. Then I can go to my wired desktop, run Speedtest and it runs fine. I then immediately run Speedtest on my iPhone and its OK. Sometimes when I don't get the network connection issue message on my iPhone, I get a Latency test failed message.
Can my wired PC cause me to lose connection wirelessly, or can being active on the desktop start my wireless to work again? I am looking for places to troubleshoot the issue. Any suggestions are welcome. Thanks.
I forgot to mention that the two Airport Extremes are connected to each other via a Netgear powerline adapter. In case I have a problem with the AE (3rd gen which is in bridge mode) or the powerline adapter, I have powered off this AE. I will see if I have any more problems with this configuration. If I don't see any problems tomorrow, I will reconnect the AE (3rd gen) directly with an Ethernet cable to the primary AE (5th gen). If the problems stay away, I know it is the powerline adapter that has gone bad.
Concerning the signal going to the modem, last week Comcast ran a new outside cable to the house and then connected it to a "new" modem and checked the signal strength. When I am connected, I get 50-60 mbps, wired.
