New RBK753S - Stability / wifi connection reliability issues every other day so far? (fw V3.2.16.22)
I recently upgraded to the Orbi AX / Wifi 6 RBK753S (from the AC3000 RBK53). I never had any real issues with my RBK53, but since my ISP plan speed just went up again, I wanted to maximize throughput...
Something to try out, Disable AX mode on the RBR. Just the 5Ghz radio or both. Up to you.
Also set CTS values to 2347. Then retest the killer adapter.
Then maybe re-enabled AX both and re-test for consistency.

Thanks. Yesterday I did temporarily disable AX mode on both bands, but it did not help with speeds, but trying to recall if I tested both laptops since it was after work hours (perhaps a good thing that disabling it did not help since I have a built-in AX adapter on my second laptop).
Let me test again later today.
I have not experimented with changing the CTS values yet though (I had been wondering about that). Let me try that too.
They are currently at 64 (default).
Appreciate the suggestions!
Well I got the Netgear A7000 AC1900 this evening (the Asus one arrives tomorrow). It is huge .
Far location (other laptop in the room all the way across the main floor, i.e. far from the RBR):
The good news, after moving it around, the A7000 wifi adapater greatly improved wifi speeds on the laptop which is located all the way on other end of the main floor; this is no doubt thanks to its antenna. In fact after moving it half a foot closer to the router (keep in mind router is in another room all the way on the other end of the floor, yet less than half a foot made a really big difference), it got around 450 Mbps!
That is far better than the 360-370 or at most 400 I was getting with the Intel AX201 Wifi 6 built-in adapter in this further location than the location below.
Room where RBR is located (main laptop):
The bad news is, just like all the other adapters, the A7000 AC1900 also did NOT get optimal speeds (e.g. only 335 Mbps vs close to 480 Mbps when all is working fine) and the Orbi did not allow it to maintain speeds on the main laptop (same room as RBR).
So the adapters are not the issue...
As soon as I rebooted the Orbi, once again magically download speeds are instantly at the top of the range again (e.g. 475.5 Mbps) and also consistent (for a while).
So something in the Orbi router appears to be causing it to lose ability to maintain a consistent wifi speed over a period of time.
The issue can be reproduced (tested with devices and signals that support speeds well over 400 Mbps) with ALL 3 802.11ac wifi adapters (listed below) I tested in the room where the Orbi RBR is located!
Killer AC1535
Linksys WUSB6400M (AC1200)
Netgear A7000 (AC1900)
I have great signals and power levels well within spec at the cable modem level (D3.1 modem) - my trusty Motorola MB8600 which was a great companion device to my prior AC3000 Orbi (RBK53).
PS: The downside of the Netgear A7000 wifi adapter is the HUGE warning sticker about the included cradle containing a very strong magnet and not to put the cradle near hard drives (huh????) nor credit cards. I mean this is a wifi adapter, yet I can't keep it near a hard drive...
Really odd and poorly thought out design frankly - there are other ways to create weight for use in PC settings without using magnets that can't be near hard drives etc...
As suggested, I set both of the CTS/RTS Thresholds from 64 (default) to 2347 just now on my RBK753S.
That appears to have caused the speedtest speeds to hit the upper range (much) earlier in the Speedtest's timeframe, whereas before it took longer to hit the higher speeds.
Let me keep that at 2347 for now. I know 500 is suggested by some to avoid potential contention / issues.
Found posts of people who had issues / disconnects with it at 64, so I am not sure why Netgear went so low (at least they could have set it at 500 or so).
Does anyone know what the default CTS/RTS values were / are with the older RBK53?
