Download speeds

I had T-Mobile wireless for four years or so. Started having problems with YouTube TV and home area, Youtube TV kept thinking I was in Detroit so I could not watch my locals. Changed to Xfinity an d it is good now.

Question is - Set the Modem-Router to have 3 different broadcasts because combine I have items that don not like it. Has to be a sperate 2g signal.
But any ways why the 6G and why faster then may desktop which is wired. Not commanding on what I get wired, BUt the ^G with my ohone oulls a=more the 1100 down vs 850 with the wired.

1. Windows network optimizations, because MS thinks, that 1W will save the world.
2. Software drivers, Windows does not like to update critical drivers, if the "work".
3. Hardware: LAN adapter, cables can make the difference, I use Cat8 flat braided.

You have to create separate networks for each band. General instructions here specific to Linksys router but basics are same with any router. Consult your brand router manual.

Ok I mean type wrong desk top is 950 plus down I know about overhead. Only paying for 1 Gig speed so it is close BUT its the wireless 6G that get me 1169 last test. not complaining .
