Three Concerns?

The mast i connect to with my Huawei B818 has cut it's power on B3 and B1 😡
Two weeks ago it went offline completely on all bands for a day, when it came back online it just wasn't the same again!
B3 was previously RSRP -99dB now its -107dB
SINR is now -4dB , previously it was +4dB.
B20 seems unaffected.
Download speeds have dropped from over 100 Mbps to under 60Mbps.(CA with B32)
Upload on B3 is now slower than B20!
I recall reading on this forum that other members have also experienced the same?
Why would Three do this?
Hi
Has your B818 been re modified?

Yes same cell IDs just poorer signal on bands 1 and 3. This happened after a complete outage of that mast for a few hours around 2 weeks ago.
I have had the same happened to me , but I am using the sercomm router provided by Three 4g plus, & a roof LTE SMA aerial.
Before last week I was getting between 50 & 170mbps . Now Getting single figure download speeds with roof aerial, but averaging 20 to 30mbps with the router internal aerial.
Because you haven’t modified, you can use the B818 internal aerials. Have you tried this?

If you're getting better speeds with the internal antenna then it's likely your roof antenna is not aligned correctly or you're suffering from signal loss through the coax cable. Are you sure you're connecting to the same cell when swapping antenna?

I have virtually no signal indoors where my router is. I possibly might take a trip to the loft or up a long ladder with an extension lead sometime again soon to see what my router can find!

How do you know it cut power?

Do you know if your mast is MBNL (shared with EE) ?

I have seen the same on my local mast, which is MBNL, from the 19th January this year. The RSSI has remained constant (currently at -59dB), but there is noise/interference and that is causing the slow downloads. My RSRQ has gone to hell in a hand cart! I can pin point that exact date using Speedtest results and went from having at least 20-48Mbps download speeds to 2-3 basically over night. I have a MikroTik dish pointing right at the mast and have changed nothing on my end!

Same mast eNB, same cell, same distance, same height/direction.

Well all I know is that the mast went completely off line for a day around 3 weeks ago and when it came back online my signal metrics weren't the same again on bands 1 and 3.
I believe its a MBNL mast. Its several miles from my home and I've never been up that close to it.
On the day it was offline Three's status checker said all was well. EEs network status checker did report a problem in the area. I was using the postcode for the mast and not for my home location.
I'm still connected to B3 + B32 because it's still slightly faster than B20+B32 but not by much.
Nothing has changed my end and even though I know of at least one band 3 mast that is closer my router refuses to connect to it.
