Slow 4G connection only, but only sometimes -- SOLVED

Itinkeralot,

Thanks for the reply.

I am in a NW suberb of Atlanta - outside the I285 perimeter.

I have looked into the MIMO antennas and getting into the box - yeah - as a ham that was irresistible to avoid looking into.

But currently - it seems - I am fine with 50M+ down and 10+ up.  I am not a gamer or streamer - and I have an advanced antenna (necessary) in the attic for TV and MythTV as my VCR - the same box running Xubuntu Linux has been at it for 11 years now … and has only required that I replaced the external video decoder box (because the first one failed).

Never had cable …

I DO appreciate pushing me to cell mapper - had not looked into it yet.

Interesting results:

Nearest 5G tower - 3 miles to West.  I have no west window.

All the 5G towers are basically next to I75.  Which handles a TRMENDOUS amount of traffic - 11+ lanes EACH DIRECTION when it hits I 285.  Ridiculous.

There is a CLUSTER of 3 tower at a park nearby  0.7 miles.

BUT there is a hill between us. A direct line to tower from my upper floor would be about 50 down in the dirt or so …

But sitting at my desk IN THE BASEMENT - no windows - my phone shows a B12 connection to a tower 0.76 miles - to the SW.  This is the only one Ihave been able to identify.

At the basement window I am connected to a B2 but I cannot find it by PCI, or any other number I have found.  Cellmapper wants not accept the 7 digit CellID from OpenSignal - and I cannot seem to make it lock onto the one that the T-Mobile can is seeing.

Unfortunately the CAN only gives PCI, Band, EARFCN.

And try as I might, I have not been able to located that tower on Cellmapper.

Also - it seems that the 3 programs I have to try to find this stuff - all disagree to some extant and worse they use deferent sets of identifiers.

For example I have found no one else that uses the eNB ID that cellmapper uses.

So at this point I still have no idea where the b2, b66, n41 and n71 I sometimes hit are.
