Repeater bridge and main router work best when they have the same chipsets and firmware.


thats wds, which is also a true proper bridge. the point of client/repeater bridge (broadcom terms) is to get a "bridge" (fake one) with the compatibility of regular client/repeater mode in double nat, without the double nat, without chipset difference mattering.

Qualcomm Atheros Wi-Fi Settings Guide


i thought i'd give you some feedback regarding this guide as i am in a wifi congested apt with two dozen neighbor routers in view of my r7500v2 running r36596, while noting SNR on four 2.4 and four 5.0 devices at varied distances of 5'-50' some with multiple 1" plaster walls between them. that guide is most helpful by informing wifi tweakers about which settings are unlikely to have any impact and why, so they don't get it in their heads that some intermittent benefit they notice actually matter.

channel width: Dynamic 20/40 is best on both 5.0 and 2.4
wide40, vht80 were consistently worse SNR for all devices.
wide40+qam256 did not benefit any of my 2.4 devices.

TX Power raised from 20 to 30 noticeably dBm levels on each
client device, but also allowed me to see more routers
which may be adding radio confusion or interference.

Multi User Beamforming causes wifi crash & router rebooting.

Single User Beamforming with 2.4 and 5.0 at 1+2+3 chains
just seem to me the most logical choice for the r7500v2,
i didn't bother re-testing for other combinations.

ACK Timing section was interesting, I left it set at 1400.

NOTE TO ALL: physically re-positioning your router,
can make a dramatic different in a wifi congested apt,
so don't just play with settings - try another room.

NOTE TO USB USERS: your device will lower the wifi SNR
so experiment with each port and wiring you connect with.
i found a fast write ssd stick plugged directly in port 2
offered the least amount of interference, when compared
to port 1 or any ssd or hdd device with a shielded pigtail
wire no matter where it was positioned from the router.
i'm at a loss to explain why, but it's what i observed.

USB 3.0 generates frequencies that interfere with 2.4Ghz when the device or connector is not properly shielded. This only apply to USB 3.0 (blue connector), not to USB 2.0

Moving the device from the 3.0 port to the 2.0 port is a workaround, but lowers the throughput to the device.

good to know, thanks Wink

on the r7500v2 both ports 1 & 2 are blue USB 3.

i tried using what was supposed to be a shielded M:F cable
between this flash drive and a port, and it didn't help,
so either the shielding was bunk or positioning matters.

Are both radios ath10k or just 2.4 or neither?

By simply turning on my Iomega 1TB HDD attached to usb port (it has a switch) memory usage jumps from 16% to 80%. Would this be considered normal? Running <Kong 36375.

Did you reset after flashing? Try a different browser? Get a new router.

that's already the 'new' router, I tought maybe this was a common problem on this device. I will go back to stock and try again.
