Never used it myself, but worth changing to say Google DNS for testing purposes as I am sure issue is not firmware related. https://downdetector.co.uk/problems/cloudflare Are you using IPv4 or IPv6 ?
Interesting, I’m thinking it’s firmware. With the router DNS not responding, I’m still able to get the internet working if setting client’s DNS server to Cloudflare or Google directly.
I’m using IPv4. Anyhow, I will have some answers if I manage to get my usual uptime with FW503.

May 16, 2019 at 11:58 am #3119I know you do (firmware vs DNS), Glad you are still testing and please do keep us informed of your results with FW503 ;-)

May 17, 2019 at 4:01 am #3129My initial observations is that FW503 is much better.
There is NO change in RAM usage after 24 hours. Previously with 585/591,I would lose 6MB each day. Perhaps the memory leaks on those firmware is having other undesired side effects.
Another note, the VDSL max sync rate is around 2Mbps higher with less FEC errors. Not sure if that’s just the current line conditions so will monitor.
I will post back in a couple of weeks if the above observations still hold true.

June 4, 2019 at 8:28 pm #3286Thank you for your interest!!! Of course i will sale the AC88U i’m very very disappointed, with AC68U i never had problems!!! And of course, i’m not going to buy again an asus network product, i feel like being a beta tester all the time… as i can see from many many users and their complains about this product!!! I will go to AVM and see if everything is going to work again. Thank you again for your time!!!
Let us know how you progress with AVM (Fritz!Box) and do not forget, ASUS do offer RT series of wifi routers which tend to work very well, especially if using RMerlins (ASUSWRT-Merlin) firmware (specific model). but a separate modem is required.
Well i finally bought AVM Fritz!Box 7590 and everything… works fine!!!
ASUS support was wrong… and they should consider to be more serious about their costumers and their software team should be more carefull!!!
My conclusion is that my FTP problem with NAS was in the firewall or the port forwarding… because not even Synology NAS could cooporate with this modem router and open ports for the FTP service.
Their behaviour force me to buy a new Synology NAS first and the Fritz!Box to work correclty.
AVM is great even for a small company… i believe not as fast as ASUS, but it’s totally stable and their software is great with no problems!!!
ASUS should follow thier example about how a modem router software should work…!!!
Thank you for listening to me and the owners to be patient about firmware problems!!!You need to login in order to vote
June 4, 2019 at 9:31 pm #3287Exactly same way I went, sold all Asus RT-routers and DSL-types and bought 2x AVM 7590 with 2x 7582 for mesh and now I am happy with my network first time after years with Asus troubles and new problems every larger firmwareupdate.
Had some hard time 30 years ago with their Fritz-Cards for Fax and POTS-56k modem installing on friends PC or laptops, so I could not believe they make reliable modemrouters now, turns out I was completely wrong!

June 7, 2019 at 4:33 am #3298Just an update before I have to turn off the power (for household maintenance).
FW 503 is the most stable for me. Current uptime of 22 days without my previous issues of the DNS dropping out or the box locking up.
The memory usage is also far superior:
FW503 – 169MB (at reboot) -> 192MB (after 22 days) ~ 1MB loss/day
FW591 – 179MB (at reboot) -> 314MB (after 22 days) ~ 6MB loss/day
I’m also convinced DSL sync is 3Mbps higher, just through observation. Perhaps the DSL drivers has a better algorithm in noisy line conditions.

June 8, 2019 at 4:40 pm #3325Hi
Besides the many issues that haunt me with my DSL-AC88U router I know have more issues
Yesterday and Thursday had issues with no 2.4G & slow intermittent 5G WiFiI powered off the router on Thursday for a few hours and when powering back on all was OK again
When I got home Friday, I had the same issues as Thursday
I tried resetting, then different FW’s, defaulting etc… but still no 2.4GWhat I noticed was the box seemed to be running hot
I noticed that the temperature was
2.4GÂ Â Â 72C
5GÂ Â Â Â 96C
CPUÂ Â Â 59CAgain I powered off overnight and today it is OK again
Temps today are currently the below and I have no issues
2.4GÂ Â Â 59C
5GÂ Â Â Â 73C
CPUÂ Â Â 50CI have the router sat on top of my NAS which is where it has been for the past 5 months
The NAS is a very cool running box, i.e HDD’s are 30CI have a Hardware Version: A1 router and just wondering if there were design/overheating issues with this model and has anyone else seen temperature issues affecting WiFi
Cheers

June 8, 2019 at 5:30 pm #332696 °C does seem a tad too hot, especially for wifi chipsets, It is getting warmer in the UK, any chance of you moving router to another location as I am sure any heat (dry air) from NAS is rising and then not helping the ASUS router.
My RT-AC86u which uses the same wifi chipset (one is same / other is slightly older) is currently running at:
2.4 GHz   –  51 °C
5 GHz  –   56 °C
Personally not seen temp that high and when I have spoken to ASUS previously about core temperatures, they say it is all expected and no one should worry, (for normal operation) as the ASUS DSL-AC88U can work in environments operation temperature (room) 0°C ~ 40°C
A couple of early firmware’s was causing issues with heat (if I recall correctly) but this was a long time ago.
Any chance of measuring air temp where ASUS is sitting ? just out of curiosity ?

I agree 96C is high, but it was 2.4G causing no connection issues at 72C
But temperature is the only thing I noticed as to why 2.4G wasn’t working, I noticed the underside was hot. I let the router cool and hey presto, all OK. I’ve stuck the router on it’s side at the moment, not ontop of the NASI don’t have a normal air thermometer, but have an infrared one and this measures the top, back and wall behind of NAS without my router on top at 23-25C
The router is showing a hotspot on the right front side around 40C
I was wondering if different hardware revisions had design tweaks for cooling
I’ve raised a support case with ASUS also

June 8, 2019 at 8:01 pm #3328I realise the issue was 2.4GHz – I was originally thinking that as the 5GHz temp was so high, this might have caused 2.4GHz to fail (?) only a thought …..
Let us know how you go with ASUS and I will ask them regarding Hardware Versions and design tweaks, I had assumed we all had Hardware Version A1 thus far ?

June 8, 2019 at 8:02 pm #3329way too hot for 5G, and also to hot for 2G, CPU is ok even very low for Asus routers.
Wifi chips have to be below 60°C and CPU should be about 70 and can go up to 80 on some routers if cooling is not well done inside (sometimes bad contact to heatsink).
Return as soon as possible or you will loose 5G or complete router!
The problems you see comes from 5G overheating 2G too beside many other parts on mainbord not designed for that high temps.
If it is a problem to return try it on your own to replace heatsinks and thermal pads.
Maybe 5G chip is already defective and thats why so hot, than cooling cant be improved.

June 8, 2019 at 8:25 pm #3330If possible, try a different physical location for ASUS router, just to ensure issue is not related to NAS or at least put on a tall box ontop of NAS ?

June 8, 2019 at 8:53 pm #3331that could hardly be 5-10°C increase!
and then it would be seen on all temps, not only 5G chip.

June 9, 2019 at 10:08 am #3340My 5ghz is at 71, 2ghz at 57 and cpu at 52. I’ve no issues. Up for 44 days, 49% RAM in use. It did rise to 56% a few weeks ago, but I had a problem with transmission, had to disable and reenable which dropped the RAM usage back to 47%. I’m not asking much of it at the moment, but it seems to be working fine.
