WiFi speeds dramatically drop when device comes back onto network

[Smokie]

I think I've mentioned this before but I think its only happening on merlin firmware. All my WiFi devices connect at full speed, until I leave the house and the come back, after I return my 360M speed est cones back with anything from 20-30M knocking off WiFi on my devices or the router and reenabling it resolves the issue. Ideally that's not something I want to be doing every day. Is there a reason this would be happening and has anyone else noticed it?

Anyone else having this issue? Arrived home today to speeds of under 5M on a 360M line. Quick off and on of the WiFi on my router and everything is back up to full speed. I don' think this happens on the standard Asus firmware.

yes, unsolved for me even on stock with both units 68U & 86U, but only on 2.4G while 5G ok while there are no other networks surrounding me.
Only 20MHz will help, 40MHz bandwith drops down to 1Mb/s, but even 50Mb/s is definitely much too slow for a 216 or 450Mb/s connection with -25dBi signal.

Starting to get annoyed now with this issue. On a daily basis I have to knock off WiFi on devices or router to get back to acceptable speeds. 2.4Meg my doors dropped down to today from a 360M line. Is this just a merlin issue or is this on Asus firmware.? I'm going to switch back to Asus firmware to test it.

The Wi-Fi is Asus closed source in both versions.

I've tried the asus stock firmware and had the same problem. Sometimes the wireless speed would go down to .2 gb/s. So far the only thing that appears to be working is moving the 2.4ghz channel and setting it manually to something that does not conflict with other routers in the area. In my case 6 or 7 instead of auto channel selection. Its been 4 days and its been pretty stable.

You sure the device that's slowing it down isn't only capable of an older wifi standard (b, g, even n)? The wifi network must always serve the lowest common demonstrator.

I have g devices and need them, seldom for special purposes, but they are powered off all the other time and cannot make any problem for n to slow down even under 1Mb/s.

And wth do you think? g devices got 54Mb/s not 1Mb/s !!!

When possible, try to stay with channels 1, 6, or 11 as these channels do not overlap with a 20 MHz bandwidth. All the other channels have overlap with 1, 6, or 11. Using 40 MHz bandwidth on 2.4 is usually problematic unless you are operating in a sparsely populated area.

only 802.11b needs 1-6-11 (US) or 1-7-13(rest), a/g/n/ac use only 16,25MHz bandwith or 20 with shoulders, so better for rest of world (not US) to use 1-5-9-13 where you could get 2x 40MHz channels!

You will never get the theoretical limits over such an old wifi standard. You could have a G router and a house full of G devices or the very latest AC Mesh router. It doesn't matter. Same reason that when you have gigabit internet and do a speed test you might get 800-900mbps on a speed test. So yes I would not be in the slightest surprised if a G device is bringing everything down to 1mbps. Like i said everything else has to fall down to the slowest device's speed once it connects. You might consider getting a 2nd AP set up for your legacy devices so your n and ac can stay at their speeds.

never had a problem with g-devices, they all reach their capability quite well!
and do you read what I wrote???
I said they turned off mostly all the time, so how could they make any problem without power???

We are speaking about 2.4G, there is no ac!
And NO, n-devices wont fall down only because g are on air, they get their time-window where they send full speed (airtime fairness will give all equal time or something like that).
g are fully compatible to n, thats the standard, only b would slow down ...

I did read it but please note I am just speaking in generalizations. I saw you posted your router models which was helpful but the OP still has not mentioned what devices they are or what router (s)he has.

I have smart connect on and my phone for example connects to the 5ghz channel. Is the issue isolated to the 2.4ghz channel?
