Time Capsule UBee Modem
I have been using Time Capsule with 2 Aiport Express - one to extend my network upstairs and the other to use as remote station for whole house audio.
Yesterday, I "upgraded" my Time Warner Internet to Spectrum - offering 100MB service. The good news - I'm getting 115MB on downloads.
The bad news - they "suggested" I use the wireless network "included" with the plan. I was hesitant, but after they connected the UBEE Modem, I was amazed at the speeds. However, if they plugged the Time Capsule and one of the Airport Express into the UBEE modem, everything shut down. I've been able to keep the 2 AEs working, as well as the 2 Apple TVs on wireless...until now. The AEs are intermittently shutting down. I have still have WiFi, but I don't have the whole house audio...and I also don't have my Time Capsule backup. I've read that it's "possible" to use Time Capsule on wireless, but...with everything else being so goosey, I'm not willing to go there yet.
Obviously, I want to keep the incredible download speeds, but I'd also like to have everything else back up and running. Any suggestions? Thanks!
