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.
Best testing for wifi would be 6-10 feet from the RBR.
Looks like the site may have had issues where posts between 10 AM or so and now were dropped even though they were 'posted' without any errors or some posts got deleted by mistake. In any case, to give a quick update:
- Router - My Orbi RBK753S (AX4200) continues to be stable now with respect to speed and connectivity (no drops) of devices connected to wifi (with RTS / CTS at 2347, downgraded to fw 3.2.17 [instead of latest], IPV6 enabled and [automatically] set to DHCP).
- USB wifi adapter - My Netgear A7000 adapter has been very steady - CONSISTENTLY getting speeds around 470 - 480 Mbps. By contrast, another manufacturer's wifi adapter is acting up again this morning with low speeds (even on 5 GHz) and also at timews only connects to 2.4 GHz); last night the competitor's adapter was working well, but this morning back to its inconsistent behavior. So I will stick with the A7000.
- USB extension cable - I purchased a USB 3.0 Super Speed 'up to 5 Gbps' USB extension cable (Sabrent) to avoid using the A7000's magnetic cradle given the big warning sticker on the Netgear cradle. Unfortunately I have to return this USB cable since speeds were MUCH lower (sometime under 100 Mbps even) when I connected my A7000 to it. Instead I may remove the magnets and maybe even the metal shims so I can use the cradle without worrying. Someone else did this successfully.
One thing I noticed with USB 3.0 wifi adapters is that they don't seem to like USB 3.0 extension cables. I found this out a while ago when I about a D-Link DWA-192 (Thermal Detonator) WiFi adapter that supported USB 3.0. Worked great but the cable that came with the adapter was only 1-2ft in length and I wanted to connect it to my PC and place in out from the PC at more of a distance. So I bought a USB 3.0 extension cable. Soon after connecting the cable I saw all sorts of problems. The adapter would disconnect or speeds would be all over the place. I talked to the Mfr and they said that the signal going across the USB cable on 3.0 can degrade over longer lengths of cable as the signal would need to be boosted some. Soon as I took out the extension cable, the adapter worked perfectly. Seems like USB 3.0 signals are effected over longer lengths of cable with these wifi adapters. I noticed that if I used the same extension cable with my external USB 3.0 HDD dock, that worked fine. I presume the USB HDD dock or external drive units provide better signal and power across the cable length vs wifi adapter seem to differ. Something to keep in mind about USB 3.0 wifi adapters.

Thanks for sharing your experiences! Your theory makes sense. How long was the extension cable 3 feet or 6 feet (if you remember)?
The cord in the wifi adapter's included USB cradle must be designed differently than 'standard' USB 3.0 Super Speed cables (the ones I got were 3 feet long); the included cradle (2 feet long) works fine with the wifi adapter. Or that 2 foot length is the maximum before thing start to get a lot worse...
Maybe I will keep these 2 extension cords for other devices, instead of returning them. Actually I bought 4 extension cords - the other 2 are the type that have a built in small base that allow the adapter to stand upright... I did not get those yet.
A bunch of people say the ones (which are coming tomorrow) work great with their wifi adapters, but nobody mentioned the mbps they were getting and a number of those reviews are from 2015, so let's see...
PS: I see that my other post from this morning is back now... :)
I believe it was a 10 footer. I still have it.
Ya seems that stock in box cables work and designed for the adapter. Anything else seems to cause problems. I didn't try any other extension cables as I relented and figured that stock cable would only be needed. Would be interesting to know if something does work.
Ya I noticed that your one post came in a bit ago. after you had posted the one before it. Odd forum behavior.
