Even then unless you're downloading gaming will always have plenty so you won't be getting bufferbloat.

If you really want to improve the value you'll need to keep experimenting with the percentages

What percentages exactly? I have seen some users that have improved in the test, putting values in the speeds that they assign to the R3, for example they put a value of upload speed quite low, this type of values should also experiment, or do you refer only to the values of ping optimizer?

The percentages vary person to person, network to network, I couldn't say specifically. You should enter the speeds you pay for/receive and then experiment with the percentages to see what works best

Then, i understand that percentages you mean are the ping optimizer sliders, that’s correct??

Yes that's correct, Congestion Control in Ping Optimizer > Advanced

there is something I don't quite understand, if I move the congestion control sliders (for example 80/90) then, when I do ping optimizer, these parameters are changed back to the ones the ping optimizer algorithm considers. If I modify the sliders, but I don't do ping optimizer, it's as if I don't really do anything.
Let's see if you can explain this point to me, because I don't really understand it.

Ping Optimizer changes the Congestion Control sliders based on what it thinks is the best option to keep your ping to a minimum, it's not always the case. So by changing them manually you're just skipping doing that test essentially and taking more manual control of what settings may work best for you.

So, if I change manually, I am optimising manually as well, so there is no need to retest, is this correct?
If so, it makes more sense

5Ghz band went down on multiple devices. This was at random. Hard wired PCs internet still works as well as the separated 2.4ghz band.

Logs attached. I only noticed 5 minutes just prior to downloading the logs (was in a game).

Unsure when it actually went offline.R3_2025-03-21T04_20_31.284Z_logs.txt

Could you reserve IPs for the devices connected to 5GHz in DHCP and see if it happens again please?

Hi, this doesn't change anything. I haven't changed anything else around the house or on the network, etc.
I have tried turning the 5GHz band on/off and rebooted the router last night.

Btw. I think I see what's happening. my work laptop (has been in the same spot forever), is picking up 1 bar wifi signal and sometimes it loses it.

Laptop is maybe 15-20' from router. It has had full wifi signal prior to this, as well as other devices in that range.

In the same 15-20', my iphone doesn't see the signal anymore. When I walk up within 2' from the router, it then picks up the 5GHz signal. As I walk 10' away, signal is lost.

If I set my PC to wifi (so removing it from ethernet cable), it can't see the 5GHz signal either.

It seems that the routers 5GHz band has an extremely weak signal that is now only usable within maybe 5' of the router.
Antennas are all screwed in and untouched, and in the upright position. Literally nothing has changed, nothing physically blocking it. 5GHz signal used to be stronger and further than 5'.

I've attached new logs.

Is that in all directions from the router where that occurs? To me that sounds like classic interference, 5GHz doesn't have great penetration either so if there are several thick walls between it and a device it will struggle. Assuming you've optimised the channel manually for it and adjusted the widths with no noticeable improvement, are there any devices within that 5 - 20ft range that emit wireless signals - not just a device that can connect to WiFi but wireless headphones for example, even a microwave would affect it when in use

Just checked. All directions are the same result.

No walls in-between my primary PC area. Other direction is at the front by the wall to outside. it only picks up signal within 5' all direction. Any further out, no signal. Before, I could go be outside 20' + through a wall and have a signal. Now no signal past 5'.

I had set the 5ghz to channel 52 as it was the least congested. I did this maybe a week ago? Since then, it was fine.

I understand microwaves and other devices can interfere. This is why I stressed nothing has changed. Everything has been in the same spots they have been in. microwave isn't running 24/7 and hasn't been moved. We have not added wireless devices, remotes, etc, anywhere here. Nothing outside either, no added cameras, etc.

Nothing has changed. I appreciate the standard checks, which is why I mentioned in my prior post nothing has changed. 

To add, we moved remotes and other small devices even further away as a sanity check. No changes to the 5gh signal.

I can try changing the 5ghz channel back to Auto, gave it a few min, checked back and it's still set to auto - no changes to the 5GHz range.

Could you downgrade the firmware to a previous version and see if the WiFi is better for you please?

[V1k1]

I've been on the latest firmware since the beta with factory reset at time of update. It was only until recently that the 5GHz band got extremely weak.

I may first factory reset on the current firmware, check the 5GHz range, and if it's still weak, I can downgrade and try that.

It will have to be later tonight.

I'll report back then.

[V1k1]

@Netduma Fraser,

I did a factory reset on v.4.0.540. No changes to the 5GHz band. Devices seem to only detect it within 5'.

I downgraded to v.4.0.290. No changes. Devices also seem to only detect it within 5'. I tried auto and assigning a channel to the 5GHz and this doesn't change anything regarding the range to exceed 5'. Logs attached for what it's worth.

To reiterate, no walls in-between where I am testing, no other online devices, no other changes to the environment when the 5GHz band used to work with OK range. Antenna's have been in the same position as well.

Literally just one day the 5GHz only reaches 5' out. At first, I thought it was simply down. It's up, just only within 5' lol.
Heck, even the 5Ghz band used to reach outside 20' through the exterior walls.

Please let me know next steps. It's been I think 3 months on this router. I worry it gets more issues with age.

I can try to unplug and plug the antenna's back in just as a sanity check..

Update: Plugging the antenna back in did nothing.
I also noticed my USB laptop fan I have plugged into the R3 router (have always had my R3 on it with 0 issues) isn't turning on. This never prevented a 5GHz signal going beyond 5' as the signal was much stronger before on the same laptop fan.

I then went and tested multiple low power USB devices on the R3 USB port and no device gets power, no phone will charge, no device will power on, no power light on it, nothing. So now the USB port doesn't work. Not sure if this got shot during a firmware update/factory reset.

Something tells me an internal part of this R3 has stopped working that feeds power/connections to the USB and/or 5GHz antenna. I wonder if the device only works within 5' because the 5GHz antennae aren't connecting to something internally, so the router loses the range the antennae provide.

2.4GHz works fine, it seems. no clue if these use different antennae, though.

To add...

I have found other posts with similar issues, so it seems it's not only me.

I have done what you have suggested in other posts below:

• Split the bands, give 2.4/5GHz different names and apply - you'll want to connect to 5GHz specifically for speeds
• Use a WiFi analyzer to find the least congested channel and change to that
• Experiment with the widths to see what gives better results
• Ensure it's in an elevated position - not on a metal surface
• Ensure there aren't any electrical / wireless devices e.g headphones etc within close proximity ~3 feet if possible
• Set the antennae to this position _ | | _

Again, literally nothing changed and just the other day the 5GHz range went down to 5' only against multiple devices (so I know it's not my phone), and my USB port isn't working. I am still downgraded to firmware v.4.0.290.

Satuday update: I did a hard reset with the button on the back for 30 seconds, waited 5 min, and still nothing has changed.

I had turned on Remote Access as I'd like someone to poke around and check anything else. Without any resolution, I would like to do a warrantied replacement/RMA.

Sunday update:
My work laptop and only my Iphone 14 pro is disconnecting constantly due to DHCP requests. I have it set to 10000 minutes as well as assigning a static IP address to the device. In system logs (added logs), you can see it constantly trying to connect to my iphone and identifying "DHCPREQUEST" and "DHCPACK". I've restarted my phone, re-assigned a new IP address, and it is still doing the same thing. My phone constantly is going on/off the 2.4GHz band and now my work laptop (unfortunately i had to work this weekend).
My phone and work laptop on the 2.4GHz band now show a weaker signal in the Device Manager even though I am in plain sight from the router (router even pointing at me) within 20'. It hadn't been this weak before. Again, no added interference. Iphone wifi settings are the same as the wives and hers stays connected.

I also received my USB Digital Multimeter. Works on ports on my PC. Plugged it into the back of the router and it receives no power. Got this to further confirm if the USB port is working or not.

@V1k1 that's interesting about the USB, do you have the router connected to a power extender or direct to an outlet? If an extender please try direct to an outlet. Otherwise do you have another power adapter you could try with? Then see if both issues are better please

Unplugged it for 5 min, plugged directly into the wall. No difference.

USB port still indicates no power.

Phone still disconnecting constantly from the 2.4GHz. No difference in the 5 foot range for 5GHz band. I even tried doing manual bands and frequencies the other night.

Please have someone remote into my router. I honestly don't know what else I can check. The router USB and 5GHz was fine before.

I want to swap to my XR500 for work but want to still allow the R3 to be looked at remotely. Should I set the R3 as an AP off the XR500? Or what would you suggest? And can someone please look at it soon? I want an expert to check so we can understand what else is needing to be looked at or if we go down the RMA route.

Someone else is seeing some similar WiFi issues so definitely firmware it seems. I've passed it on to see if we can have a look, if you could do the following:

If your ISP modem/router has WiFi, set it up so that it is in bridge or modem mode, you can also use the DMZ. Copy the WAN IP from the R3 (found in Settings > WAN) and enter it into the DMZ function on the ISP modem/router. Disable IPv6 in LAN/WAN on the R3 and enable remote support in Settings > Troubleshooting. Then post back here from a device connected to the R3 when you've done that and we'll attempt to connect when available.

Hi Fraser. I've seen other posts around the wifi and USB as well. Thank you for passing this on.

I'd love to know if they find anything around the wifi and USB issues. I've even downgraded to prior firmware which didn't change anything, so wonder if something bugged out or got stuck due to an update/downgrade, or anything else.

I'm posting from my desktop hard wired in to the R3 which has Remote access turned on.
My modem doesn't have wifi, so I've left it unchanged and have left other settings unchanged.

Please also check the logs I provided in my prior post. Something else seems to be janky in the DHCP world. Although, today seemed better for my work laptop. I haven't caught my phone constantly disconnecting from 2.4ghz like it was from my logs, but it may still be doing it if I watch it closely after work here.

Quite possible it has gotten itself in a weird state, I've let them know you're accessible and so hopefully they'll be able to take a look. Unlikely to be today but you don't need to be present, they can connect any time now

Thank you Fraser. Please see if they can get to this within a few days. It's already been some time without 5GHz working properly and the USB port.
Should I keep anything unplugged from the USB port until this is checked?

Mainly wanting my 5 GHz range back and USB to power on.

It may be a good sanity check to see if anything else is in a weird state that would be related to the USB and 5GHz. Maybe the 2.4GHz is next lol.

No need to do anything different. They'll let me/you know if they need something specific
