You are welcome. I was thinking if you know the distance to the tower from your coordinates it would be good to look at the coverage for the n41. I believe it only spans our maybe 3 miles. If you are on the outer fringe maybe that would account for the signal being unstable. I know I am 5.3 miles line of sight to the tower I am connected to and it is sending on n71 so my signal should hold pretty stable. The price I pay to be in the rural area with the mountain view. :slight_smile:  I just wonder if the radios operating on the edge of the delivery reach for the signals tend to waver from time to time. I am sure the throughput is lower as the radio is farther away from the tower. Probably follows the same basic physics as WIFI signaling in that respect.  Good luck with it. 

I’ve also discovered that occasional reboots are helpful. What’s aggravating is that I can’t find an easy way to do that other than signing into the web portal. If you unplug the gateway, it just runs on battery. Has anyone found a quicker way to reboot?

Power down(on/off button). I also unplug the unit, plug back in after 30 seconds, then power on.

If you want to really do a power cycle you can use the power switch on the router. I have unplugged the can but well if the power switch is ON then well the battery will deliver power for the tower radios. Just use the switch on the back. Allow the router to sit for like 30 seconds or so to allow capacitors to drain down and then power it back on. It will take approximately 2 minutes to fully initialize. Once it comes back I like to use an ethernet cable and login to the HTML UI to review operation and make any changes  I think necessary.

You can connect to the web UI with 192.168.12.1 via the wireless as long as associated with the WIFI signal. I find using an ethernet cable better. That is my preference as the WIFI on my MacBook Pro seems to be a little less reliable than some of my other clients.

My modem dropped off n41 today and fell back to n71.  Still decent speeds but definitely slower.  A reboot brought me right back up on n41.  Looking at my previous posts I think I had similar issues last Sunday only I fell from n71 to nothing on the secondary channel.  I have my speed test app checking speeds every 6 hours.  My downloads have mostly been above 150 Mbps since my reboot on Tuesday.  Today they dropped below 100 Mbps.  I’ll increase my speed tests to hourly for a while to gather more data.

Hum… When you pulled the secondary signal with the RSRP at -111 dBm was that with the n41 or n71 channel? If that was with the n41 connected on the secondary signal that would put the reception at the outer cell edge. According to the tables I have found RSRP <= -100 would be defined as cell edge. I really would find out the coordinates of the tower that both the n41 comes out of and the n71. It may be your router is at the outer edge of the n41 but solid in the n71 so it tends to fall off the n41. Just speculation on my part, but knowing your coordinates in relation to the tower the signal originates would for sure provide some clues. I would ask T-Mobile if both the n41 and n71 are transmitted off the same tower. I would think so. 

I really think much of the disconnects are related to the tower gear. The 5G delivery even on n71 seems to be rather flakey to me. The signal currently is not even present as far as my router is concerned. The 4G is delivered from roughly 270 degrees which is NOT the same tower here. Until T-Mobile gets their 5G network a bit more mature I think we are going to continue to see delivery that is unpredictable.

Yesterday for hours the 5G connection was absent so I gave up on any serious work online. Today it is back. I am not sure when the 5G signal from the tower at 0 degrees started up again as I did not monitor it. It is back this morning and pretty much as it most commonly is. The 4G LTE signal commonly appears to be delivered from the tower at 270 degrees and the 5G signal originates at 0 degrees 5.3 miles away. So far this behavior has little variation and I have not seen other than the n71 channel here. Since we are in a rural location with lesser population density it stands to reason they would use the n71 for broader coverage. The speeds we have here with T-MO are 10X our service in CA for less cost it is harder to complain about but the unpredictability tends to be similar to PG&E electric service in CA. Doh! That is not a compliment. I hope your connections improve. I think given time the solution will mature and become more stable.

According to my scheduled speed tests I was on n41 from 8/14 @ 1:20pm to 8/18 @ 5:24am.  Then I dropped to n71.  Up until now the back of my modem has been pointing just west of south.  They should add a compass app to the top screen!  I rotated it clockwise about 45 degrees and rebooted.  I came back up on n71.  Then I rotated it counterclockwise 90 degrees and waited.  No change.  I rebooted and it came back on n41.  I will be interested to see how long I stay on n41 this time.

According to my last post I was only able to stay on n41 for about 88 hours.  I was relying on an app on my phone to do scheduled speed tests but I don’t think it was very reliable.  I have since switched to running them on my computer.  On Sunday night (8/22) my internet went out completely.  It had not done this for a while and seemed unusual since I had rebooted the modem a few days earlier.  I did not rotate the modem and just rebooted it but it only came back on n71.  It was working so I left it alone for the night.  By morning it was still on n71.  I rebooted again and it came back on n41.  So I’m thinking there was an issue with the tower the night before that made n41 stop working.  I didn’t fall back to n71 until today and with my more consistent speed tests I can say I was on n41 for about 98 hours.  I find it interesting that my time on n41 seems to be limited to less than 100 hours at a time but I’ll keep rotating and rebooting to gather more data.

I did another 45 degree rotation counter-clockwise and rebooted but only came back on n71.  I went back to the previous angle, rebooted, and reconnected on n41.  So I only have 2 angles that get me on n41 so far.  Interesting.

Either I’ve had my modem pointed the wrong way for months or the tower in town has been getting better.  I was able to stay on n41 for over 11 days before falling back to n71.  I made another rotation and was able to reboot on n41.  I’ve never seen my SNR higher than 18 so it must not be the strongest signal.  I’ve only got one angle left to try whenever I fall back to n71 again.  I also did not get the firmware update yet.  Although I did only do a soft reboot and not a hard reboot.  Does anyone know if that matters after a new firmware is downloaded?
