1 of 3 R310’s is underperforming

[jan_willem_henn]

Dear community,

I have 3 R310’s in my home, two downstairs and one at the third floor.

Unleashed setup, firmware 200.7.10.202.121, wired connected via 1000mbit, PoE af switch (netgear).

Roaming works well on AP’s, but WiFi speed on AP’s downstairs is at max speed (300mbit), WiFi speed on the one upstairs is max 70 mbit (close to AP). WiFi range on this one seems very low as well.

I have checked the performance of the lan cable by connecting my laptop, which is full 1000mbit with no package loss.

What I have searched so far on the forum:

- there seems to be a performance issue (for over two years now), halving download speed compared to max. But this seems unlikely, since 2 of the 3 are performing really well. Option would be to downgrade to 200.4. But then I miss a lot of improvements?

- interference in unleashed network. Could that be the case, since they are transmitting the same radio on the same channel? Seems unlikely as well.

Any help is greatly appreciated!

And, by the way, it would be not normal that all 3 APs use same channels, channels actually are expected to be different on all APs.

Good catch...... I did not read the same channel part 🙂 since I read it quick 🙂

Thnx, I have separate ssid’s for both 2.4 and 5. My issue is with 5 ghz, perhaps also related to the fact I only enabled channels 36-48. Please see my last comment for my latest update!

Ok, think I fixed it. 

Hard reset of the slow AP did not do anything, so indeed swapped two AP’s.

now the swapped one still not performed at max speed, but a lot better than on the previous location.

then I decoupled the AP on the third floor from the PoE switch (802.3af). Perhaps capacity of the netgear switch was too low. I added the Ruckus PoE injector at the one one the third floor, and all 3 AP’s perform now at max ISP speed (300mbit).

will try for a few more days and let you know the outcomes.

thanks for the help so far!

btw. I previously only enabled channels 36-48, resulting them to stay all on the same 80mhz channel. Now also enabled channels 52-116.
