Hello, this is my first post in this forum, so please be understanding.
Two days ago I bought the B525s-23a router together with the lte T-mobile INTERNET MAX internet offer. I set the router in the best possible place using the Network Cell Info Lite application (I transferred the card to the phone and checked the whole house including the roof). Strangely enough, I got the best results on the 1st floor by the window (standing on the roof above this window, I got worse results?).
Here is the screen from the roof, in the room I obtained -92.
When it comes to speed tests, I have a good lottery.
And once I was able to have "even" 26 Mb / s. So you can say that depending on the time and I do not know what it gets from 1 Mb / s to 26 Mb / s. For PLN 80 a month it is a pathetic result and I would like to do something about it but I do not have adequate knowledge. I thought that the antenna on the roof could somehow help, but since the measurements from the roof were worse than from the room in which I currently have a router, that's probably not the problem.
Do you have any idea how to improve the quality of the connection?
In addition, I am surprised by one thing, the router generates two wifi networks 2.4 and 5. Amazingly, the 2.4 network has a much better range, what could this be caused by?
Thank you in advance for all the help, I've only had Internet for two days, but if you can't do anything about it, I have 14 days to return, so I have to act quickly so I don't get stuck with such an offer for two years.
