Check your antenna cable paths and reseat the connections to eliminate that as a possibility. I hope it's not hardware.What could be the cause of the sudden drop in signal? Is it likely to be a hardware issue of software issue?
RSRP of -86db does not indicate on any way loss of connection...RSRP better than -86db
RSSI value is completely useless ... the same way as voltage measured over wire pairs on UTP when assessing ethernet throughput. RSRP at least gives information about level of usable signal while RSSI includes also noise, interference and channel load (traffic for other clients of same cell). However considerable drop in this value would indicate something's wrong with attached antennae and/or Rx part of LTE modem.You should take into account the ... RSSI values too...
Is there any value you take into account the most ?
@mkx how can it be useless since it is used in the calculation of the RSRQ value ?
I think all the values ( RSRP, RSRQ, SINR and RSSI ) have their importance...
Is there any value you take into account the most ?
As a side note, there is another part of the infrastructure that could be accountable for your problems.What could be the cause of the sudden drop in signal? Is it likely to be a hardware issue of software issue?

Yeah they got the largest chunk of the 5G spectrum so it's nice to see them moving quickly to roll it out.3 uk are doing a lot of mast upgrades, adding 4g bands 28 and 32, plus 5g n78
Mine is plug and play on V7, it's an interesting comparison to my r11e-lte, r11e-lte6 and em12gThanks for the advice guys.
I've updated the modem firmware and the ROS to 7.2.1 - getting exactly the same results.
I've ordered a Quectel ec25-e to see if the issue is with the modem. It arrives tomorrow.
I believe this modem is compatible. Does anyone know if it's plug and play?
Going from cat 6 to cat 4 is a bit of a pain but I could get the cat 4 modem from Amazon with one day prime delivery.It seems it is... and in V7 you can use the APN profile as well https://help.mikrotik.com/docs/display/ROS/Peripherals
But you will go from an LTE cat 6 modem to an LTE cat 4 ?
Yes, arrived late morning and got it fitted and connected to Band 3 only. Sadly no discernible difference grrr! Pretty much exactly the same signal as before.Has the Quectel EC25 arrived?
Here are some photos of what I found...

Are Vodafone and 3 UK the best options in your area?So, in the last couple of days I've tried a Vodafone SIM. I can see the mast about 2 miles from my house. Pointed the dish directly towards it. No matter how much tweaking I do I cannot get speeds better than I can get with my mobile phone standing right beside the mikrotik.
Today I did a teardown of the lhg. Was pretty surprised to find a little rust on the routerboard antenna and some rust staining in the housing. Clearly isn't waterproof!
I can't see any noticeable damage to the board but would query water damage now.
I have dug out an old Huawei router and a mimo antenna I have. Going to give it a go later to see if signal is any better.
