Bell Fibe (Canada) with Asus RT-AX88U Pro running firmware 3004.388.8_4 appears throttled

[Philip Bondi]

Hello to all:

My Bell Fibe connection has been rock-solid on the Asus RT-AX88U Pro. I have a post on the same.

Episodically, Bell seems to throttle my connection.

Are you seeing this behaviour?

Your screenshot is too small to read. But if your speeds are always around the 94Mbps area perhaps your WAN Ethernet link has dropped to 100Mb. Check the link speed in the router's webUI.

Check the logs as well. Maybe Bell is doing something. More likely a cable/termination/port issue though.

I use the SpeedTest app from OOKLA on my PC and I consistently get the below on Bell Fibe. Downloaded the app from the Microsoft Store and no issues for my 86U Pro on a HH3000. Anything less than that and your speeds will likely tank although I'm not sure you can use FIBE on anything less than a HH3000. Make sure they gave you at least a GIGA HH4000 modem as that's the latest I believe and what all my friends that got FIBE recently are getting from Bell.

I had to RMA my router last year because the 2.5Gb WAN port started negotiating only at 100 Mbit. The 2.5Gb LAN port still worked fine. It was never “episodic” though. It was consistently 100 Mbit until repaired.

Thx v m

Thx. I've reposted the content. And depicted configs with .pdf instead of screen capture.

HOWTO: Bell Fibe with Private Cloud; port forwarding; email, web & Plex servers running!

Yes. I think this could be my problem. I've swapped to an Asus RT-AC68U (which never held pppoe connection reliably). And the RT-AC68U delivered 940Mpbs up/down to my other devices. Itself, it's too slow to bench 940Mbps up/down. Lol.

I'll open tech support case with Asus about my RT-AC88U Pro. And try the other port for WAN uplink.

I'm on bell fiber for about 5 years now same router no issues with throttle ever and i've been on many different asus routers with merlin in that time frame.

It might have something to do with the tariffs.

I could not get the secondary port to operate the internet service. I've telephoned Asus tech support twice. It appears that the 2.5 Gb LAN port works as a LAN port. But when configured in Dual WAN mode, the 2.5 Gb LAN port does not work. In Dual WAN mode, modem cable is recognized only by WAN port. Regardless what is designated primary or secondary.

And further after all these reboots on the router, I'm getting 940/940 Mbps, again. So the 10% or 100% performance remains "episodic".

You were given advice in posts #2 and #3 which you appear to have ignored.

Cable, port or compatibility to ISP equipment issue. Someone has to look at System Log on this Asus router at some point.

I inspected my logs. I could not find anything conclusive. Anyway, after several reboots. And trying Dual WAN feature to switch to 2.5 Gb LAN port, the speed is now meeting specification.

Thanks very much for coaching.

If I were to search, how should I search the logs? What would I be looking for? FYI my logs get pushed to my Linux server, so I can search on the Linux server. The last reconnection that resulted in 10% speed appears to be Jan. 17.

grep "RT-AX88U_Pro-E2C0-D08DAD1-C" /var/log/messages-20250119|grep -B25 -A25 "WAN(0)_Connection"

I designed this search to discover pppoe reconnections. I don't see anything within 25 lines of reconnection that is insightful. But maybe you can.
