No Ranging Response received - T3 time-out

Hi all,

I know this has been posted before, but after a bit of research I'm confused as to whether my levels are fine or not. I'm a bit sick of being on constant hold to Virgin media, as it seems I have a new problem with them every day!

We recently moved and took Virgin Broadband with us, and everything seems fine for the most part, although I did notice I wasn't getting a great connection in some areas of the house. I bought an AC86U ASUS router to fix this, but I've been having a few issues that too, and I can't figure out if the problem is with that or Virgin.

I'm trying to narrow down where the problem is, however, I have noticed that my Hub 3 (now in modem mode) possibly has high power levels on the downstream channel. I tried to explain this to someone on the phone (after a ~30 minute wait), and I'm not sure if this was because it was another issue asked after solving an account issue (my new account didn't show up when I logged in online), but he just said reset the router.

However, I'm not sure what an acceptable level is. I've read some places say it should be between -7-7 and other places say it should be between -15-15.

I'm going to guess they're not, since every few days I'm getting the critical "No Ranging Response received - T3 time-out" in the logs.

As an aside, one of the big issues I've had with the asus router is that things tend to drop sometimes. I can only tell this from the "access time". Is this normal behaviour for something to just sort of reconnect to a network every now and again and thus that access time resets? Or should it be constantly connected to the network? The main problem has been with the 2.4ghz band for a laptop, I'm wondering if I should've gone for something different to help the wifi signal (as buying another one of these to make a mesh would be expensive, and I've not had the best experience so far!)

Thanks.

Re: No Ranging Response received - T3 time-out

Yes the downstream levels are too high there.

Regarding the AC86 router - if you look online there are some batches that have issues with the 2.4Ghz band dropping or just outright failing altogether.

Re: No Ranging Response received - T3 time-out

All hubs have a few T3 timeouts, and every few days that's not a problem.  If there's lots of them, or they are appearing with other partial service and sync errors then that is a problem.

Regarding power levels, general accepted range is -5 dBmV to +10 dBmV, but the actual details are considerably more complicated for reasons I won't bore you with.  To have the range of power levels you've got, I suspect power is probably too high, so I'll flag this for the forum staff to advise.  Response isn't very quick at the moment, but they're doing their best.

Regarding the Asus, I'll leave that to people with experience of that kit.

Re: No Ranging Response received - T3 time-out

Thanks for advice, look forward to hearing from the staff and hopefully can get it resolved soon.

It's hard to work out what the issue is. I notice it on my work laptop which is the only one that connects to 2.4ghz. I'll stall on my remote desktop, go to a webpage on the actual laptop desktop to check, and when you click on a link it'll just not do anything (doesn't even look like it's loading). It looks like it's getting kicked from the router, but you don't notice without looking at the access time, as the wifi on the computer never looks like it disconnects.

Even though it's not the best connection, most of the 5ghz stuff stays connected up here, so it's weird the 2.4ghz doesn't. I actually bought the router as I thought the range would improve a bit, as I was getting a few disconnects with the hub 3. One of the reasons started looking outside wifi connectivity.

Probably should've just bought a bundled mesh system in the first place now I know more!

You can configure your ASUS router to work with other ASUS “AI Mesh” compatible systems
