The reason for low signal level is distance - 16km for 3.5GHz is huge. The only reason it somehow works on one of your devices is that the interference is almost non existant (NR SINR at 26dB) which will change with more people using 5G in your area and with MNO adding 5G transmitters to other towers.
and your screenshots say so (n3 band NR RSRP at -105dBm is marked as poor). ml#pid1377Ĭontrary to your beliefs, 5G signal you're receiving is poor. The whole thread is here for anyone interested. Why is the mediatek able to connect no problem whereas my other 4 devices all have this same issue. and the A22 5G has a Mediatek Dimensity 700. The common thing between my devices is they all have a snapdragon X55 modem. I was really surprised about being able to connect to N78 since I am 16 km away. I then tested my partners A22 5G phone connects no problem though with really good speed results, on both N78 and N3. I manage to catch a screenshot of when it briefly connected before losing it. It will keep doing this in a loop every few seconds and will not hold onto the N3 connection. It will show N3 for a second or two then disappear and all the bands will aggregate differently. on the chateau 5G it is something similar. It will just keep failing to connect every few seconds.
So I have 4 external antennas connected to the chateau 5G, so I have even better signal than the A22 5G has. (Swapping A5 with A6 and connecting A0 and A1 to the ANT 2 and ANT 3 ports.) details of modification here:
The chateau 5G is modified for use with external antennas by using the u.fl to SMA cables. I assume the routers would be able to as well. One thing to note is my S20 connects to N78 and N3 on every other site I've been to while travelling and also when I drive closer to my serving cell. However the A22 5G has no problem getting 500 Mbps down and about 60-70 Mbps upload and it connects to both N78 and N3. Regardless of where I select N3 only on the mikrotik 5G router or not. Three Ireland upgraded the site and deployed N3 here so I thought I should have no problem getting that but the same issue occurs. I initially thought in the past the 5G symbol flickering from outlined 5G to full white was something to do with N78 band being unable to synchronise the uplink since I am 16km away. The *#0011# SIM information readout on my S20 says : RACH_PROBLEM and the 5G symbol keeps flickering from outlined grey to white over and over. I have a netgear MR5200 + Mikrotik chateau 5G, and a samsung S20 + A52 5G and they all cannot connect to the 5G from home. Ill link the thread below but basically with even more detail. Hello, trying to figure out an issue with 5G where I live, I live about 16 kilometers away from the serving mast from Three Ireland with direct line of sight.
