This is NOT in my wheelhouse..  So I do not know what version hardware or firmware this is and admit I have forgotten how to find out.  

Its so long in between issues, thank goodness, I forget what I did, how I did it.

I am getting the 1 gig service through the modem (at 900 mbs) hardwired.  But the same computer is barely getting 350 over wifi and the computer is setting next to the router. 

The specs on this router (purchased in 12/2023) says I should be getting that 1 gig or at least 800.  Only have two streaming TV's, two computers, two cell phones, none all on at the same time

Are there any tweaks I can do to up the signal on this router before I trash can it.  Not looking forward to purchasing another unit.

And yes, someone will have to hold my hand until I remember how to get back into the router online  Sorry but thank you so much.
