My 5G HI gets slow, then speeds up after reset

I am new to the 5G Home Internet package from TMobile. Initially, the system was fine, speed was acceptable no problems with YouTube and Roku streaming.  Lately, within the last couple weeks, during the early evening hours, say 5-7 PM, the system starts slowing down. Sometimes it gets so bad that I can not get on the Internet at all.  And here is the kicker: All I have to do to get it to go back to normal is just reset the router.  Today is a good example: around 2:50 PM, I was getting 540Mbps x 14.50Mbps.  Then at 5:01 PM I was down to 27.85 x 0.21.  I do a reset, and I jump back to 300 x 18.60.  

I spoke with Level 1 CSR and finally was speaking to who ever is in Manilla and was advised to place the router as close to the window as possible.  I even had the router on the windows sill, but the morning son shines thru so I moved.  I found a sweet spot just below the window and thought I had resolved the issue.  But and that's when it went down to  27.85 x 0.21, and resolved it by the reset.  

Anybody have any thoughts on this?  Is it my router?  Ask for a replacement?  Go back to AT&T?

Thanks.

    I think (And hope with fingers crossed) that I might have figured out the problem.  I was using my own TPLink Wireless access points through out my house, and not the built in WiFi coming from the TMHI Gateway.  So I got rid of all my WAP's and setup the 3 TMHI WAP's I had requested when I first got the system.  And it seems that things have stabilized.  I have not had to reset the gateway since doing so, and have not had any speed issues.  The only problem I have now is my devices seem to hop to a different WAP or connect to the gateway at random times, not necessarily being the closest access point. If go and reset the device, it will hop back on the closest one.  Go figure.

  • I'd recommend to 'start' with a replacement, however, I'm doubtful that this will permanently fix the issue.  I've had similar issues when using VPN (worse, actually) and items such as Zoom.

    Typical speed was +800Mbps hitting upto 1Gbps.  Using VPN drops down to < 6Mbps.  When I switched over to Spectrum (kept in parallel for testing).  I had a 100/10 connection, speed test gave 100Mbps w/o VPN, and 100Mbps with VPN.  Replacement gateways worked 'for a while' until patch level caught up to current.  These all started after October 2024 when T-Mobile started pushing firmware updates.  I had to cancel TMHI service after +5 gateway exchanges.
