Horrible signal to noise ratio

I CAN!!!!

To take full advantage of the n41 the 4x4 MIMO antenna is best. When researching the external antenna solutions one of the techniques to reduce noise is to use the structure as a shield from unwanted signal interference. With my solution I found that to be helpful. Installing at a higher point is not always the best solution. Improving results does take a bit of experimenting for sure. 

Odd I wish my reading looked half as good as yours you have great signal compared to me.

I am averaging 50-80 at best so no idea why you have such slow speeds. But these things are finicky moving them even a very small amount yields big gains in speed.

I don't see you listing it what are both your primary and secondary signals? I see the B2 but you should have 2 like this.

This is what I have. I honestly don't know if it's good or bad. I just can't understand apart from the terrible signal to noise ratio why my connection is so bad.

You are very close to the 5G what you need to do is put the can on a long ext cord move it around even inside your home. Test many spots sometimes you will get much better speed with a little less signal bing inside. I mean you have such good signal strength you should find a spot where you get 100+ off that n71.

I really hope so my friend. Right now as you can see in the attached picture my router is up in a ceiling window that is facing the tower which is the next street over. I don't believe it's a 5G tower though. That is why I cannot understand the whole signal to noise ratio problem. I've got two fans running one on top one of the bottom. I even have a black out shield on the window so the sun doesn't hit it and it doesn't get hot up there. It looks pretty messy and butt ugly! But when I try to make it nice and neat the signal was even worse. If I move around my apartment like you suggested I will be going away from any windows and going more towards the hallway of the apartment complex. This will be going in the opposite direction of the tower. But I will take your suggestion and give it a try.

This is my set up. It's in a window that is as high as the ceiling. And that window is facing the tower. As much as I moved the router ever so slightly in that window it would either make no difference or would make the connection worse. The window is blocked so no heat can come through. And there are two fans one on the bottom and one on the top of the router. It looks pretty ugly. I tried to make it nice and neat but that only made the signal worse. I will definitely try your suggestion though. Although any other location in my apartment is going to be further away from the tower and closer to inside the apartment complex which will be closer to the hallway.

Looks nice.

Do keep in mind that there are 4 antennas on the unit so rotation can Improve download speed. Look you will find many post that say signal is not the best indicator download speed is. Also many post that say moving the unit indeed did make the signal worse but somehow made download speed faster. Since you have great signal and are complaining about speed why not give rotation a try you have nothing to lose and all to gain.

I am in a second fl window facing the tower. Just did some more speed testing (don't care about signal) rotation changed download speed in a range of 25 to 80. So when I find the spot that gives 80 I fine tune it. I have tape with marks so I can move one tick at a time and test.

So just give it a try.

Also you will find post where again no one knows why but they get much better speed with the can inside and less signal. So don't get hung up on the signal if you want speed try moving it.

Attempted to move my router all around my apartment and unfortunately the speed got progressively worse as I tried. So I put it back to where it was before and unfortunately now the speed is much slower than it was before I moved it!

My signal to noise ratio on my primary signal is 0 dB!  Obviously you can't get any worse than 0 db for signal to noise ratio! I also noticed that my band on my primary signal has now changed to be B66, where this afternoon it was B2. I don't know if that change was what made things worse.

You had mentioned that I'm very close to the 5G. How were you able to determine that and is there anything I can do on my end besides moving my router? Does the secondary single even matter? The reason I'm asking is it seems I'm not even using the secondary signal despite it being there so is everything relying on the primary signal? It sure seems that way because I get the feeling the secondary single is not even being used. I wish there was someway I could get them to have the point at the secondary signal and make that the primary one.

First I would only run one fan and make sure its blowing bottom to top and you have spacers under the fan so it can draw air in from under it. Fans can cause interference noise sometimes, one at the bottom blowing up is more then enough to help push the passive heat dissipation faster. You can out a piece of single layer tissue on top to see if the fan is pushing enough.  I noticed sometimes if you turn the fan a certain way it can push more.  If this is a 12V fan you wont need to run it at 12V as that could just cause more noise interference so I suggest running it at 5V from a USB power supply. 

Have you done a full default reset on the unit since you found a good spot with the good secondary signal? I have also seen others mention that it needs to be unplugged for 3 minutes before plugging back in. Maybe the secondary signal is active but not fully online yet?  You could call T-Mobile and ask, or maybe they dont know the tower is having any issue unless you report it.

Mine is running the same channels of B2 primary and n71 secondary (see attached picture).  I have attached my speed test results also. I found that because of the way speedtest does the test sometimes the servers cut back on the upload speeds, so I started running it from my router that's that I use off the ethernet. My router is 22 feet away on the other side of the room. I did this to also avoid unwanted interference as listed with the FCC Part 15.
