Buffering or dropping altogether

[msufans5]

Hello!  I'm new to this forum and have a question.  Last week we finally got upgraded to the Xfi Advanced Gateway.  It was a nightmare but it's on.  

After this upgrade and a plan increase to download speeds up to 1000 Mbps we are seeing more drops of internet on computers/phones and far more buffering on the TV.  Honestly, it wasn't this bad with our old system and my family feels as if this was a poor choice.  I'm thinking the pods might help but we didn't need them before and we survived OK with few minor glitches.  

Any advice for a not too tech savy individual?

Thank you!

For a test, does a computer hardwired directly to the router / gateway device with an ethernet cable have the same problem ?

I'll have to check that out.  It hadn't occured to me to check so I'll do that and report back!

We are trying to determine whether it is a *WiFi-only* problem or an overall connection quality problem to / with the Comcast coax system.

It seems to be working fine when connected via ethernet.  We just seem to maybe be dropping wireless connections?  I'm at a loss but streaming TV, a college & high school seniors doing online learning and I'm working from home.  With all of that 4 days a week I guess I could see some issues with dropping out but weekends the number of devices on the Wifi is less.  

Any other advice?

There are other options. Google for WiFi repeaters / range extenders, WiFi mesh systems / pods. 

Good luck !
