Im on 591 and yeah i don’t use ai protection anymore and frankly the router is more stable. I’d rather have my full speed internet of 330/50 than the tiny bit of protection trend micro offer with slowdowns and problems to boot. To be honest all you need is common sense on the web.

@UK Sentinel  It is interesting indeed, What Asus should say in their fancy overview on their product page or even in a FAQ of the support page is “our router is compatible with G.Fast connections, but to fully utilise your line speed you can’t have certain features on that we provide” Same goes for any other stuff they provide. Or they could be blunt and say just buy our router with all these non promised features than may or not work and use default settings.. :D

To be fair i think we’ve hit the point like we did on the previous DSL routers especially like the 68u, where there is lack of support/consistency of stable firmware’s etc. This however could be down to a multitude of things, the main one being is they have a poor team developing the firmware and have no idea on how to fix the problems even after various users submitting feedback. The other thing could be they’re trying to ride out these problems but are concentrating more on their next DSL flagship.. does anyone know if the latter is true or false?

Also @UK Sentinel i admire your persistence and determination in dealing with the Asus team ;)

Went very well indeed, with ai on and off achieved full download speeds with low cpu usage, no stutter etc

So to confirm speeds over 100Mbps and ai protection on this cpu is too weak to handle the demand of inspecting packets. Other than that and the IPV6 issue the firmware is fine for me as long as ai is off.

 

@cozak

Yes we already know about the Nat being disabled when ai is on, i was just merely stating since i see no other user other than myself on G.Fast which is affected more by this. That’s why i asked if other users on lower speeds experienced what i did when ai is enabled, and as above my friend who is on 80/20 not affected in anyway when ai is on with Nat being disabled.

For ASUS NAT Acceleration (CTF) I believe (I think) the speeds was around 150Mbps , but as you correctly say, AiProtection disables (CTF) and thus cpu maxis out. I will chat with ASUS and see what they say?

Yes that will be good to hear what they say ;)

I have a friend that is near and is willing to let me test out the theory of the NAT acceleration with ai protection on and off tomorrow, he has same ISP as me but is on 80/20 package, so i’ll report back to see if it has any difference :)

Going from memory i believe when ai protection is enabled and the nat acceleration is disabled because of the packet inspection trend uses that will affect anyone with speeds of 100Mbps plus. However it may be fine for people like you with 50Mbps and people who are 80Mbps as the nat acceleration only really comes into effect when above a certain speed like 100Mbps.

The processor is only a dual core 1GHz, so this is interesting, I will pass this back to ASUS to see if they have any comments, but do not worry, they will not contact you I am on a 50/10 service and previously not noticed any speed reduction Are you on IPV4 or IPV6?

 

So in that case ai protection is fine for connections below 100Mbps.. any speed above that and it struggles when enabled.

IPV6 is not working for me, in fact it never has since i got the 88u. It was working fine on the 68u router but on this 88u it gives the wrong prefix like another user on here. But i saw recently you said Asus are looking into the issue?

Since this morning ive been on latest official 591, as expected i knew the outcome of my testing but ran them anyway. Ai protection may have had an update but the trend micro engine is still centre of problems for me anyway. I still think the intense workload for Ai to work properly is too much for the cpu of this router especially under heavy usage the router begins to struggle.

Ai Protection = Off

Full connection speed 330Mbps in steam downloads etc,

Low cpu usage and memory usage,

3 wired 15 wireless devices running seamlessly.

 

Ai Protection = On

Losing around 100-120Mbps in speed of my 330Mbps connection,

Both cpu cores maxing out to 100% when any type of heavy usage, like downloads from steam, watching multiple streams on Twitch etc causing router lag and degradation in performance for other connected devices,

Nat acceleration being disabled due to trend’s packet inspection could be why my speeds suffer when heavy usage is applied and also why cpu usage hits max constantly.

 

I’d be interested to see if people who have got connection speeds below 100Mbps are experiencing the speed decrease with ai on like i have or if they’re still getting their full speed?

Even though its an official release, I’m still very sceptical of any firmware created by them. Who knows, Asus might surprise me and have fixed things they claim in their release notes… or created more problems ;)

11 days since my DLM got reset and back up to my 330Mbps Down, 50Mbps Up, connection and has been stable on the official 585 firmware. Ive learned to live with the 88u. Ive had no issues with my speed, or with high cpu usage/mem usage when under high load etc. Since the majority of issues revolve around the ai protection ive just left it disabled as its more troublesome than its worth when enabled. To be honest if any user has the knowledge and common sense its not really needed. Another reason why my speed plummeted i think is because with ai on, the Nat acceleration gets disabled for precise packet inspection. Users that are below 100Mbps might not be as affected as me when its on.

Memory usage usually hovers around 37%, max ive seen is 42% and thats with 3 wired desktops, 16 wireless devices under heavy usage. Cpu usage is very minimal too. No dropouts on the wireless either.

Things ive changed:

2.4 & 5ghz – airtime fairness disabled, preamble type short, All beamforming disabled

Upnp disabled

Dos protection enabled

Static IP’s for everything

@UK Sentinel

ASUS are starting to annoy me now, for one they’re not listening to things ive mentioned in their email reply’s. They keep bombarding me with debug firmwares and saying test test test. Not even considering that Ive told them i can’t do any tests that correspond with my speed issue with ai protection on because im not getting my full speed now because of the previous testing lead to me having DLM, thus meaning the tests will be nullified and waste of my time. Still not listening…. sigh.

Now just because i said i reverted to their stable 503 firmware and declared i had no problems with the speed or ai protection prior to my DLM, they’re subtly hinting that i have not configured or noticed if its truly enabled or disabled. Basically trying to pass the blame as it were to the end user/customer. I like to note since March this year i ran on 503 no problems, with no disconnections whatsoever. Perfectly stable. Only time i disconnected was to update the firmware when the 585 was released.

I was alright with helping them at the start but now im not and i feel like a guinea pig, just because they’re useless at their job. Its sad it has come to this because the hardware inside the 88u is solid, its just the poor creation and delivery of firmwares which has destroyed its potential. Im now done with this and exploring different avenues now, whether or not they will read my latest email reply stating i can’t help them is like saying “how long is a piece of string” . If you can help at all since ASUS respond to you UK Sentinel that would be good ;)

Also apologies for the rant :)

Wish i had that at the start rather than BT sending me their rubbish all in one hub. Then i’d have MT992-10 and a RMerlin supported router ;)

The MT992-10 is so hard to get a hold of now, next time i see an openreach dude im gonna ask if i can get one or something similar that is G.Fast compatible. No harm in asking i suppose ;)

Ouch!, so ASUS Engineer is saying, AiProtection can/could reduce you internet speed, so ASUS are selling a unit that is suitable for G.fast speeds, but only if you do not use AiProtection (maybe).? I do not blame you for not assisting any further, but thank you for trying Edit: I spoke with ASUS and they say Your email said, you would look into it, so best let them know your decision also?

 

Yeah i replied that i could not do further testing due to the impact on my line, as i have no idea when the DLM resets itself. If it takes more than 2 months though BT will be getting a nice… phone call :)

I did stress in the email back to ASUS though that i was concerned that they’re advising customers to turn off a protection feature to achieve full speeds and turn it on when finished downloading. It should work regardless. People should be able to setup their modem/router and forget about it, not constantly going in and changing things etc.

I mentioned that i reverted back to 503 as that has been perfectly stable for me, no issues like others have faced like DHCP, wireless and stuff. I also told the engineer that they should analyse 503 and work from there and see what has been done to the ai protection and they said they’re going to do that, and they will notify me if there is any discovery. At this present time im feeling very sceptical.

Well i got a reply from ASUS, and to be expected not really helpful. Looks like they wanted me to test another firmware that looks the same to be honest but i can’t because ive been heavily hit by the DLM, line got rebooted throughout the night now severe download impact and high pings.

I just assumed it was normal and it probably is due to the power demand going from VDSL2 to G.Fast. If my values are that and I live right next to the cabinet, i wonder what values other users have who are on longer lines. Im sure i read somewhere that G.Fast is more limited in length than VDSL for customers. Especially if BT are promising a minimum guaranteed speed of 100Mbps for G.Fast and if they can’t deliver the speed promised customer gets reimbursed.

Line Attenuation Upstream Value has never been displayed, This is a Broadcom limitation, I did notice your Downstream SNR value is very high, are you running ASUS STock585 firmware build?

After my testing of 585 and feedback to ASUS etc, i reverted back to 503 and im staying on that till the next stable no problem official. From what ive gathered from 2 engineers plus a friend that used to work with BT. The G.Fast values are different to the non G.Fast connections and cannot be compared. Yes G.Fast uses the same setup but its values differ from VDSL2. To note again, the values have been the same on 4 different firmwares on 88u. Also same values in the smart hub too. :)
