#1 about backhaul is right now over my head and will do some reading and check with the local tech that from the IT division that takes care of our WiFi.
#2. “What band is your client connecting in? 2.4 GHz is usually more crowded than 5 GHz, so if your client is associating in 2.4 GHz… you’ll likely see less performance.” Client is connecting to 5 GHz for both these ACs
#3. “What are the capabilities of the AP? If it is a good, 3x3 AP, great. If it’s only 2x2 or 1x1, then you’re going to see less performance, because it can’t hit as good of data rates. What is the channel width? In 2.4 GHz, we’re pretty much limited to 20 MHz, but in 5 GHz, you can use a 40 or (sometimes) 80 MHz channel. I like to make my AP’s match across the board - I always use the same channel width on every AP.” These are ExtremeWireless AP 410C’s with 5GHz 4x4:4 spec. Both display that they are using an 80 MHz channel width
- Is the second AP on a worse channel? Maybe it’s a congested/crowded channel, so it performs worse than your first AP. Very improbable as my apartment is at the end of hall and for since this new WiFi building coverage was installed I have had no neighbors in the two adjacent apartments that are actually opposite each other. I do pick up two other access points with slightly less strength but better than -70 which must be on the floors below and above. However remember this is a continuing care facility and in these apartments reside us older folks with most very uncomfortable with technology let alone change. Most were using Comcast or Verizon as their ISP’s and I few have yet changed to the “free” new service
I will spend some time with the tech tomorrow and post what I learn.
