constant disconnects and slow uploads...

RouterOS Wireless Networking
1

I have thre AP’s, all with the same issue. each AP has anywhere from 4 to 10 clients on it, and anyone below a -75 disconnects pretty regularly and has slow upload speeds. Even some client that have signals as high as -68 will disconect! According to Ubiquiti, I should be able to have client connecting as low as a -85!!! I simply dont see how this is supposed to work. Can anyone shed some light on this. Here are the settings of the AP and the Client unit:

Try putting the power settings to default and turn off nstreme.

Also, you might want to consider upgrading to 2.9.26, they have fixed alot of bugs and haven’t published them. I know 2.9.46 helped fix alot of issues i had.

What is your noise floor?

You have done a very common thing. You have messed up the rates. It is a big mistake to change settings without understanding what they mean. I suggest you default the entire box and start over. The goo news is that everything will work fine when you go back to defaults.
