I am trying to find a way to use my cellular Hotspot as a backup internet at home and need it wired.  I bought the AC750 RE220 for the wired port.  I was successful extending my cellular Hotspot from my phone.  If I use the extended wifi signal, I get great bandwidth but when I wire in a laptop, it drops to around 4 or 5 mb down and up.  I also need to wire in a meraki VPN and when I do it drops even more for upload, .6 of mb. Any suggestions?
