Hello all:

Please bear with me as I have several questions here.  So any instructions/advice would be greatly appreciated.

We've always had TP-Link routers and extenders, and just over the past week I purchased two higher powered units, which are:

The TP-Link BE6500 wireless router

The TP-Link BE3200 Mesh Extender

The issue that we are experiencing now is that we also have a Panasonic wireless phone system at home, and we basically have 5 phones (one in each room).  Prior to getting these new TP-Link devices, we were having no issues with static, crackling noises, etc.  Our previous TP-Link router and extender combination were the AX500 router and the AC1200 extender. 

However, now that I've connected the new TP-Link units, we are experiencing noisy phone lines.  I'm guessing that the wireless signals are conflicting.

So my first question here is, "Are there settings within the Router that I can adjust to choose a different frequency range, so it doesn't conflict with our home phones?"  I'm sure there's an easy fix for this, but I'm a novice with all of this.

2nd question involves this:

Within my settings, I noticed a selection called:  OFDMA/MU-MIMO.  To the right of that is a drop down box with 3 choices:

OFDMA+MU-MIMO

OFDMA Only

Disabled.

Right now, by default, it is labeled with a "Disabled."  My question involves, "What does this do?"  Should I select one of the two choices (other than disabled)?  I have a regular home WiFi setup that we're not sharing with anyone else.

Thanks so much...
