Flex box streaming buffering issues

I am new to Flex, I installed it per instructions and my internet package is the up to 400Mbps.  First few days I was getting buffering watching movies via Flex.  I tested the wi-fi speed in the room with the Flex, download ranged from 20-70 Mbps.  On a morning call, First level tech support couldn't fix the issue and scheduled service call for house the next day.  That afternoon, Advanced Tech support called me and within about 15-20 minutes the bandwidth was now in the 300+ Mbps range near the Flex.  problem solved right?  I thought so.  That evening, I accessed HBO MAX through Flex and the buffering was still there watching a video.  I tried access account info through Flex and it locked up.  I then tested bandwidth speed on two different devices near the Flex and the speeds where in the 300+ range, so what is the issue?  I decided to accessed HBO MAX through Firestick, to test a optional streaming source ... not a single buffering all evening.  Seems the flex box has issues with maintaining a stream without buffering.

Any on else having buffering issues with Flex box?

Hi there @jb_c! Thank you for reaching out to us here via our Forums platform. I am sorry to hear that you are experiencing issues with buffering while using your Flex box, is the issue still present? If so, have you attempted to reset your modem?

@XfinitySelena Yes resetting and more before a tech came out yesterday.  Ended up switching out modem/router and flex box.  so far things are good.

Oh that makes me happy to hear that the modem switch helped and that now you can watch without issues! Please do not hesitate to reach out here if you ever need it. You can also send a quick reset signal to your modem directly from your My Account at your convenience if ever needed! Enjoy your weekend and thank you for being a valued part of the Comcast family.

Buffering has returned not as bad though.  When it happens, I do a speed test from the room with the flex and the bandwidth is in the 40-60 Mbps range, the buffering clears and bandwidth is back in the 200+ Mbps range.  I guess this is common with the Xfinity equipment.
