Wifi Dropped only on.2.4GHz, 5ghz working Fine.


[link to this post]
 
Asus n56u and BT modem.
2 PS4's connected via lan using Lan adapters.
3 Iphones and a ipad using 5ghz signal.
2 laptops using 2.4ghz signal.

Now the problem I have is I get 42mb DL & 5.9bm UL speedtests for over 5 years on all devices wired or wireless. I have not moved the router from its position or added any new devices to it.

The router is on channel 13 for over 5 years as my neighbours are using ISP supplied routers and fight over 1,6,11.

Suddenly overnight all my 2.4ghz laptops started running slow to kpbs in speedtest and then shoot up to 42mb or sometimes start at 42mb and drop all the way down.

I've double checked surrounding wifi channels and no one is on my channel 13.

I even checked the iphones using the 2.4ghz and it the same, but work fine on 5ghz.

I contacted my ISP and they say all good on line and no faults show and telephone works fine.

So I decided to swap out the router with ISP's and it started off good, but eventually went downhill like the Asus n56u.

I could do with some help here, if anyone has experienced something similar.

Many thanks

If you are only seeing the issue on 2.4Ghz with the laptops, and have changed routers/Wifi APs, thenthe issue may be with the latops - are they both the same hardware spec?

What has changed on the laptop?
Driver updates
s/w Firewall
OS

Could you try a USB wifi adaptor on one of the laptops?

Or a device is co-sharing the 2.4GHz spectrum now, e.g. neighbours wifi or some other device

Not just laptops, I put the ipad n iphone on 2.4ghz and does the same, Laptops different models and specs. Its All 2.4ghz problem no matter what device I use.

But have you looked what wireless connections are being made to your router is the question. Nothing to do with what other wireless SSIDs/routers are near you.

My broadband basic info/help site - www.robertos.me.uk. Domains, site and mail hosting - Tsohost.
Connection - Three 4G, tbb tests normally 35-45Mpbs down, 65Mbps off-peak, 9-24 up.

Only my devices are are on router, no change in years.

I use as stated in original post, mixture of 2.4ghz n 5ghz, Only 2 items are 2.4 and all others 5ghz. But for test purposes i switched between 5ghz to 2.4 to diagnosis. I hope thats what you were referring too.

Channels 11 and 13 overlap by quite a large margin.

It could be that your neighbour(s) on channel 11 have added more devices or are just transferring more data.

Your choice of channel 13 will not be helping anybody:

https://www.metageek.com/training/resources/adjacent...
&
https://www.metageek.com/training/resources/why-chan...

I would use 1, 6 or 11. Given 13 is poor, try the opposite end of the spectrum e.g. Channel 1. Plenty of APs now only have the option to select 1, 6 and 11 as channel options as vendors have noted adjacent channel congestion is causing problems, and increasing returns etc.

You may get lucky using 13, as some APs will try to "avoid" using 11 once they realise there is adjacent channel congestion on 13, and revert back to 6 or 1. This naturally degrades performance overall. This probably explains your years on 13... APs are increasing in power however, and this behaviour is changing, where vendors realise their 7 antenna device will overpower post APs.

To check, you are using 20MHZ right?

Have you tried the router on AUTO?

A fixed channel is not a great idea in today's climate where we have Bluetooth keyboard, baby monitors, headphones (Apple AirPods, beats x etc), mice, etc which all use 2.4Ghz.

Check out 1 and 6...See how you get on.

& right now you have co channel congestion as you are using 13 which "overlaps" with 11. The only channels you should opt for are 1, 6 or 11. Most devices follow this rule.

Since 13 is performing poorly, it indicates 11 is likely to also be poor since they are overlapping channels. Hence, let's try to move away from 11. The only way to do that is 1 of 6.

Having several WiFi points on the same channel is how the specification is designed. Performance is best when all Wi-fi routers use 1, 6 and 11.

I have 30+ APs in range of my office, all except 1 is on 1 6 and 11. Works acceptably.

[re: jingerman] [link to this post]
 
Great... if everyone took your approach and used overlapping channels throughout would grind to a halt much quicker.

The issue in basic terms is WiFi bonds together multiple channels to get faster speeds...

channel 1 overlaps with 2 and 3.

6 overlaps with 4,5,7,8

11 overlaps with 9,10,12,13

When you have 3 devices on channel 11, they try to work nicely together by "waiting" between transmissions for the other APs transmissions to complete.

However if you have 2 devices on 11 and 1 on channel 13, the 2 devices on 11 try to work nicely together, however the device on 13 is not "seen." Hence the device on 13 will transmit at the same time as devices on 11, packets will collide in the air and not reach the destination (eg laptop phone etc).

The packet will require being resent, hence now there is twice as much wireless traffic as the packet is retransmitted. If it collides again, that's 3x etc. Eventually everything grinds to a halt as data is just retransmitted over and over, never getting where it needs.

Just choose the best of 1,6 and 11. There's nothing more you can do.

The long term solution is to ensure future devices are 5GHz.

2.4GHz performance is not great, I am in London and even at home I have excessive interference. It's common to see speeds below 10Mbps in busy populated areas on 2.4GHz.

Give 1 a go, as it's furthest from 13 where you were having issues.

EDIT: What AP are you using? ISP kit?

Is it possible your device is failing?

It would be odd for interference to be across the whole 2.4g band.

Fair, I would personally pick the best Speedtest on 1 6 or 11 and see how you go.

I can't say my Speedtests are very good. Usually 11PM is the worst speeds I get, which is common as users head to bed and stream on iPads etc.

On 2.4 I vary from almost no throughout (like struggle for a 320P video) to 50Mbps...

I do live in a new-ish build block of flats however. The way the flats are setup I pickup everyone's AP on my floor with strong signal (4 other flats) and upstairs is quite strong too.

I have got everything other than a printer and a tv on 5Ghz now... although I do need to get around to splitting the SSIDs as devices often stick on my 2.4. The smarthub type b seems to do some sort of band steering close up.

EDIT: great shout on the 5GHZ adapter front!

Tried plusnet hub and it does same thing, all ok on 5ghz but overnight a week ago 2.4ghz flopped intermittently, for the 1st time in years.

Got 6 virgin isp's around me, varying from 1,6,11, but my rssi is lowest at 61 n nearest is 66.

It is hard to say with any absolute certainty...

Virginmedia speeds can be 300Mbps, but often more like 100Mbps. Even then, one AP has the ability to saturate the whole 2.4GHz channel if a user is downloading.

Older VM hubs used to split the 2.4 and 5GHz SSID by default, and users would opt into 5GHz as it was faster. Since the Hub 3, they now have same SSID, and hence most users fall into 2.4GHz...

It could be as simple as a couple of users have upgraded to the latest VM Hub, and now many more users are on 2.4GHz... It could also be something entirely unrelated e.g. a cheap baby monitor on 2.4GHz that someone purchased.

Most likely it is a combination of things.

If you get chance run inssider - it lets you see visually the channels in use by APs and the overlaps of channels. It can be quite useful for choosing a channel.

https://www.metageek.com/products/inssider/free/

It also makes you realise how 5Ghz overlap is likely to be a problem soon smile

By the way my neighbours moved in recently and I can hear baby crying. Your theory of baby monitor might be spot on. I cannot tell them to turn it off ?

Baby monitors can certainly cause a reduction in performance. I have one of the BT camera ones that appears to cause slow downs on devices that are at the furthest reaches of the house when it's on and in a certain position. However, this is no different to when next door moved their routers location (signal went from 1 bar to 4 bars) and I would see drops or slow reactions at certain times on 2.4ghz network.

Obviously you cannot tell them to turn it off as it's their house to do as they please and you don't have a right to owning the airwaves in your own house. You could however overpower their signal by putting the mesh network devices around your house.

IMO using channel 13 while your neighbors use 11 is more likely to cause issues than someone using a baby monitor.
I get zero issues with a baby monitor in use.

Well today, I couldn't even connect to 2.4ghz channel on any device, No internet access secured.

So finally the 2.4ghz radio signal died. Replaced with isp router and everything fine. bye bye asus n56u router RIP

I bought netgear r8000 with 6 antennas and still 2.4ghz issues, went through all 13 channels and only 13 gave more then 15mb all the rest about 5mb.

Used inssider to determin neighbours channels and rssi.

I get the lowest rssi but still issues.

It is very common for 2.4Ghz to give very poor performance. Plenty of offices I work with have disabled 2.4Ghz entirely, others have band steering enabled, as the interference in densely populated offices areas is so high the throughput grinds to a "halt."

We are starting to see situations where 5Ghz is also problematic on channels 36, 40, 44 and 48 due to 80Mhz being used.

Regarding equipment, ISP kit is usually more than adequate nowadays for the general population. I have a nighthawk device (a few years old now), my TalkTalk Hub outshines it significantly on 5Ghz range.

Firstly my statement was that a new ISP supplied device, outshines a device which is many years old. I never stated it outshines a 6 antenna third party router for 200 pounds..

That being said, to be factual the BT Smarthub, BT SmartHub 2, and TalkTalk Hub have 7 antennas. The SmartHub 2 and TalkTalk Hub are Wave 2 AC devices, the X6 R8000 is not Wave 2, and has 6 antennas not 7.

Looking at the Talktalk Hub the wireless is an antenna array of 4x4, vs the X6 R8000 at 3x3.

Looking at throughput tests including Toms Guide, a Netgear X6 R8000 gets a downstream throughput at 5ft of 302.3Mbps on 5Ghz.

ISP Kit p9

This compares to major players ISP Kit as follows:
TalkTalk Wireless Hub 713.9Mbps,
BT SmartHub 713.9Mbps,
Virginmedia Hub 3 726.9Mbps,

The 5Ghz chip on the x6 R8000 is 2x 1300Mbps chips, so single device throughput is restricted to AC1300 on 5Ghz. BT and TalkTalk supply kit which is 1733Mbps at 5Ghz.

Also your 2.4Ghz issues will likely be made worse by this device in the default configuration of 600Mbps and not 20MHz.

On the PlusNet One Hub, have you tried splitting the SSIDs? Connect as much as possible into the 5Ghz band... You can do this on any router too, e.g. the Asus. Whatever cannot connect to 2.4Ghz will perform poorly, any possibility of upgrading this to 5Ghz? What kit is stuck on 2.4Ghz - apologies if you have already stated I haven't got the chance to re-review this whole thread just yet.

There's options to get onto 5Ghz even for TVs etc.

Only 2 items on 2.4 both laptops, ps4 wired via powernline no issues. everything else 5ghz ok.
Only 2.4 headache no matter what device. Same on 3 routers, PN/Asus/Nightgear r8000.

If laptops are used close to main router have you considered something such as this?
TP-Link Archer T2U Nano AC600 Wireless USB Adapter, Dual Band WiFi Dongle for PC, Desktop and Laptop, Supports Windows 10/8.1/8/7/XP, Mac OS 10.9-10.13 https://www.amazon.co.uk/dp/B07LGSDBTF/ref=cm_sw_r_c...

This would give you 5Ghz on the laptop. For further distance there are larger models with antennas.

Damn that's bad.

Update I reported No Internet Secured error to ISP, they said they'll monitor for 72 hours. Today I receive text saying The fault no longer appears to be there so closing ticket.

And everything is back to normal like 5 years ago, single/multiple speed tests full Mb/Dl on wireless.

Very very puzzling.

It is a wireless shared medium, so performance will vary depending on usage in the local area on your section of the spectrum. E.g. when you use channel 13, you experience is very dependant on users on channel 11. All it takes is a neighbours router to reboot, and per ISP default configuration, on AUTO channel selection it may choose channel 1 instead of 11... This could then result in your wireless speeding up, especially if they use the wireless facility heavily.

Naturally, their router may choose to come back to C11.

Or it could be they have left the router on, and it's still on C11 but their usage has dropped extensively e.g. gone on holiday.

My worst time is around 10pm to midnight... People take the iPads and phones to bed, usually away from the router and fall onto 2.4GHz, they then proceed to stream some netflix, iplayer or whatever... Same for the kids etc. This is when my streams get stuck at the 240P.

Anyway, 5GHz is the answer for now although I am noticing already in my area some slowdowns.

EDIT: There have been rare occasions where I have not even been able to connect to my AP on 2.4GHz without changing the channel. It's a real pain!

Yes, you were correct it worked for a bit then boom down to crippling speeds, even took laptop next to router and still getting crippling speeds on 2.4ghz, must be major interference somewhere. Even at early hours you expect ppl to be in bed and its bad. Only works ok when powerline ethernet connected.

I've even managed to move router closer to our devices and see -49 RSSI and have the best signal compared to neighbours, but still no joy.

Yep, you're in the same situation we were when we lived in an apartment. Everything was fine until we got neighbors and then their 2.4ghz was stronger than our own in our own apartment!

The solution that ended up keeping the wife happy was to increase the speed on our plan and set the router to automatically manage its own channels so it will hop around like all the other routers were doing. Setting a static channel never worked for long.

Good luck!

I have also found 2.4ghz to be the culprit of low speed and this is in a relative large 4 bedroom house and being in the same room as the router. The signal around the house shows as fine (min of 4 out of 5 bars) so it's not bad signal.

I am not living there at the moment, so assumed it could be a problem with Virgin Media's network as whenever I went there I was lucky to get 60mb/sec through my iphone, and moving around house it could drop to 20mb/sec. As soon as I restarted the router it would get a higher speed (but still no where near max) so for along time I put it down to Virgin network and thought I'd deal with it when I move in.

Couple of days ago I was having issues with my CCTV so decided to finally have a look.

I turned off all the auto channel steering functionality as apparently this doesn't work well on VM. Tried changing 20/40mhz on 2.4ghz but as soon as the router restarted it would return to 20mhz. Tried changing channels between the usual 3 options 1,6,11 to no avail, might get a little more speed but not much above 80mb/sec.

So I separated out the 2.4ghz and 5ghz networks (would rather not have to do this) and problem solved. On 5ghz it's getting the full 200-220mb the connection supports. Even in the furthest away from the router still gives well over 100mb/sec. In fact, on 5ghz I could still get over 60mb/sec at the bottom of the garden or drive at either ends.
