Networking question

I’m in the midst of an interesting challenge. My DSL internet connection went out (12 days ago, and AT&T is STILL trying to figure it out). In the interim, I’m switching off between using my phone and iPad as hot spots. I can enable both the wireless connection on the PC that I use with my Flex, and the ethernet connection to the switch, which also has the Flex connected. Then I tried both sharing the wifi internet connection and bridging the two adapters (ethernet and wifi). They both result in the same thing - SmartSDR starts and sees the Flex, but errors out trying to connect to the Flex. I have to disable the wifi connection (and, hence, the internet connection to the PC) for the Flex to see the PC. Does anyone have any suggestions on how to resolve this? It’s not a huge problem, because I can use my iPad for all the internet related stuff I was doing on my PC, and keep just the PC ethernet connection enabled. However, it would be nice to have both working at once. Thanks - David, AG4F
