Home Internet Goes Out Every Couple of Hours

If it doesn't stop I'm gonna leave for Comcast.

I gave up a consistent 12 Mbps for this.

You may be in/near my market (also get "homed" to Charlotte here in Florence, SC).

Might want to watch your signal stats in the Home Internet phone app as you move/rotate the modem around.  The tower options/levels may have changed a bit.  May be able to lock a different band/tower with less congestion issues now.  Remember, stronger signal is what "looks" like lower number at first glance:  -89 is MUCH stronger than -92.

Been a LOT of changes recently.  Sprint  towers have been coming online, but signal levels have been a bit screwy.  Used to be able to easily swap to move between bands 2, 4, 66 amongst 4 towers by just shifting it a foot or so and turning a different angle.  Bands 71 and 10 just started showing up randomly, but 71 is the only alternate in that direction that seems to come up regularly.

Lately it is getting harder and harder to grab 66... it is a about 1/4 mile further then one of the band 2 towers that seems to have ramped up it's power a little.  Just under a mile from me, reorienting the modem has gotten me to where I can keep that band 2 around -88db, sometimes as high as -86db... but have yet to see it hit -92 or worse like the others tend to do.  When throughput goes south, it tends to plop me on band 4 for a while, then it flips back to that band 2 without me having to nudge it anymore. CQI has also been staying mostly 8 or better with it in this one spot (as was explained to me, that is basically an indicator of your prioritization level).

Also may want to select a different location to test against.  Routes to Charlotte tends to be considerably congested.  Probly why Spectrum uses Raleigh more often than Charlotte in their pathing from here.

Can type in a city and see a list of carriers to test against.  I like to use a Century Link in Seattle alot, as that is also Level3, a BIG peering partner for the southeast in general--lots of transport bandwidth in play, which helps to narrow down if erratic latency is more localized or not.  Alternatively, I'll hit some sites in Montreal as that tends to lean towards Cogent and TATA for the peering (other big names in the US).  If you go elsewhere along the Canadian border, you may get some Verizon in the mix (ALTER.NET), which can be very touch and go.  If you go the central/southern Cali or southern midwest spots, that tends to be Level3 and Zayo alot--not consistent which one will be in play, so it is kinda hit and miss.

I'm having big-time issues with my home Internet. It goes in and out moment to moment. Trying to do anything becomes an ordeal. Watching videos is a struggle with constant buffering. I am getting sometimes incredibly high speeds of up to 180 megs, but this doesn't translate into smooth operation at all. I wonder if they are gaming the speed test system.

I have had this same issue. Here is a youtube video showing a screen grab of my macbook clearly showing service to the gateway with wifi signal broadcasting but nothing actually happens. Has anyone successfully gotten support from T-Mobile for this? When I call I only get scripted "reboot the gateway, lets reboot from the interface". I've done all of that and it tends to work for maybe 6-30 minutes and then I have to do it… AGAIN. This is literally my 10th reset today. 

Link to my youtube screen recording: 

I signed up about 2 months ago ($60/mo, just missed the $50 price) and ran the 5G gateway side by side with my Comcast and finally decided last week to cancel my 19+ year Comcast service. This week my speeds have gone to $hit and I notice  the gateway is not connecting to the secondary signal anymore, just a slow B12 band no matter how much I restart. I just read in another thread someone who is going through something similar said he needs to reboot his gateway from the app every few days after removing the ethernet cable to his existing router, then once it reboots, he can plug ethernet back in. Last week when I switched over,  I plugged in my existing router permanently via ethernet instead of just testing it for short periods. 
Note that I have NOT yet tried this type of reboot, I literally just read this in another thread and then I saw this thread. I am curious if the others here experiencing the slow downs are also plugging in a router of sorts to the gateway via ethernet and wanted to pass this on in case it's a workaround of sorts.

That was an interesting concept-- my increasing problems the past month after my gateway working great the first month or two pretty much correlates to the warmer weather. I happened to have a 4" computer cooling fan on hand and set it up under the gateway, and it has made a difference, but is not a solution. My ~1 Mbps download during the day is up to ~3-4 Mbps -- a far cry from the ~75-100+ Mbps I was getting. I think my main problem is either related to my home wifi network now connected via ethernet or the fact that I got a primary and a secondary "good" connection for a few months, but since the problems started, it's a "Very Good" Primary signal and NO secondary signal no matter what I seem to try. I just dumped Comcast, too. I'm about to sign up with Centurylink. Anyway, thanks for the "hot tip"-- can't believe I didn't think of that sooner myself. 

Adding myself to the list of people impacted by this issue.

Sometimes the problem clears up itself. It could be minutes or it could be hours before things start working again.

The problem is bad enough that I have order a watchdog outlet to power cycle the Nokia modem if the Internet connectivity is down for a few minutes.

I hope this issue gets resolved soon so i can resume the relatively stable service I had before.

Adding to the pile here. It cuts out every few hours and needs to be rebooted. Sometimes will cut out 3 and 4 times an hour. Was promised I would have 5bars and can't get any stronger than 2 no matter the location. 

I called support and they were polite but just told me engineers were working on it but could provide no other details. 

I hope a rep comes into this thread to shine some light on this as it's clearly pretty wide spread. 

I don't know if this helps or not, but I've had the white box (4G/LTE ?) for several years and this also has been happening to me for the past several months. I used to get 35-50 speed all the time and now it will be 3-8 until I reboot the box. Then it goes back to 35-50 for awhile. So it's not just the new towers.
