How do I physically disconnect the diversity feature as well as some of the filter mess to save it from eventual suicide?
Not sure about a physical mod, but in the firmware you can select either one to always be used.
I've had trouble with it not tolerating different antennas, not tolerating only 1 antenna of any sort, and randomly switching antenna jacks.
Since it doesn't have the obvious hardware "Y" via chip, like a Linksys, I've been considering a hardware mod in order to run dual-biquad, yagi, etc. . .
The unit does seem to be overly filtered at the output, making itself ill.

Sorry my friend. The only involvement that could possibly interest me concerning this piece of shit radio requires sledge hammers and / or KV range high voltage transformers. _________________ http://69.175.13.131:8015 Streaming Week-End Disco. Station Ripper V 1.1 will do.

Well, the radio is the same chipset as many of the Broadcom devices; however. . . This particular circuit board has some extraneous counterproductive parts in-between the radio and antenna jack, plus 50 ohm circuit traces that resemble a traffic jam. It is the location of the "shit" that you mention, because there is literally junk in the signal path of an otherwise excellent radio.
Colloquially speaking, your description is accurate, except not the radio itself, but rather. . .
This circuit (between radio and antenna) is physically different than a Linksys, and thus the firmware selection of antenna ports doesn't work reliably, especially after a reboot.
Edit: I'm not sure if its cause (execrable circuit layout not compatible) or if its effect (very irritated radio not eager to accept alternative antennas). And, I'm not sure where to install a bypass.
Plug in the wan to get initial access working and then put
Code:
nvram set vlan1ports="0 5"
in the startup script (and save it) to straighten out the Rosewill's port assignment.
In the photo attached, notice the "bufferbloat" score is an A, which also means almost no latency. It could be used as a gaming router. CPU load was at 9% with 15Mbps cable. Perhaps it could even do 50Mbps cable. I suggest to set the wifi to g-only, afterburner on, frameburst on.

The Rosewill's lesser wifi range can be resolved by replacing the mostly plastic antennas with these with more metal inside: https://www.ebay.com/itm/252317415888? 12x200mm, 6dbi. After refit, wifi survey can confirm reception range is greater.
It is curious that neither smaller nor larger antennas that I tried had worked as well for the Rosewill.
Inside is an oversize brass thing, an inch long coil and a solid copper whip that goes nearly the entire length--quite a bit more material than expected for $1 apiece.

It is 2018 and I am still using my RNX-GX4 as my main router. It is extremely stable, reliable and never-ever requires to be re-booted or looses signal. I've configured DD-WRT on the router to run two DHCP servers on two separate isolated sub-nets with dedicated virtual SSIDs and even redirected one of the physical ports (one sub-net for me and one for the kids and guests).
I have other N and AC dual-band routers that I use as access points off the RNX-GX4, but it is my main "control" router and it is also my fall-back WiFi router because of reliability.
Also, a few years back I replaced the antennas with 12dBi antennas and forced transmission power to 100mw which amazingly boosted the transmission range. These are the antennas that I used for anyone that still has this router:
BTW, I am currently using DD-WRT ver.3 release "01-19-2018-r34578" (Firmware: DD-WRT v3.0-r34578 std (01/19/1). Very stable and reliable. And, with the replaced antennas, I get amazing signal strength.

Are you using the dd-wrt.v24_std_generic.bin?
I too am still using my RNX-GX4 with dd-wrt, but I've been negligent and need to update.

Thank you so much for news about the firmware.
Recently, my cable company made a change to a faster speed, they said. My newer model atheros routers turn on all the LED's flashing like crazy while slowing down to a crawl; so, the 9 year old Rosewill came out of the desk drawer.
I had some doubts.
However...
This is working so much better than expected.
It has no problem routing 38 megabits (I paid for 30), videoconferencing, laptop vpn, browsing, ip phone, streaming, with multiple users, all simultaneously.
Aside from brisk web pages, the most noticeable difference is when asking the Google Home for the temperature, there's no more duh. . . . . . delay, but instead, it responds instantly.
