slow wifi speeds with c7000 and xfinity
My internet speed through my computer (ethernet) is 350. Using wifi on my cellphone on 2.4, the speed is only around 70. This occurs when phone is next to modem/router or 20 feet away. Changing to...

If you're only going 30 ft with a wall in between and the 5ghz isn't reaching, I'd be looking at that wall. 5ghz penetrates much less materials than 2.4ghz but 30 ft is within the distance that 5ghz should cover. Certain materials like plaster lathe, adobe, tile with the metal underlayment can all block wifi signals.
How are the speeds when the wall isn't there?
If its just the single device/room causing issues it tends to be either the device or the room thats creating interference.
do you pull full speeds if you're hardwired to the C7000?

I pull full speed when connected wit wire. Between 350 and 400. That is why I questioned using my phone within 1ft of the modem/router and getting only 79 on 2.4 and 159 on 5g. Main problem appears to be at the source

have you tried any other wifi devices? A single wireless device isn't conclusive and many things influence wifi speeds. Thats why we base most of our diagnostics off hardwired speeds. To many things that can cause issues over wifi.
Also try backing up, 1 ft is a little close.
Tried changing wifi channels?
What channel are you currently on for 5ghz?
What speeds do you have set for your 5ghz wifi?
Again, your 2.4ghz speeds are expected. I wouldn't expect to get much better than what you are for 2.4ghz.
