Hi,

Couple of days ago I upgraded to AC87U.
But I'm having some serious problems with it. I really want to just throw the s*** out.

The problem I'm facing, is first of all. The signal strength to my PC at second floor (router is in first floor), is bad. It is only one signal bar. I can not even find the 5GHz connection that is set up as well. On my iPhone next to the PC I can find 5GHz network.

I have tried all kind of combinations for the antennas, but still no improvement.

Second, I have a 100/100 broadband. I am only getting like 12/6 and 15-20 ms ping. Before I upgraded my router I got like 2 ms ping. My ISP tested and got 1 ms.

I have tried every channel from 1 to 13 (beside 5 and 12 because I could not find any network when I chose those two channels) on 20 MHz bandwidth. 40 MHz do not make a difference.


Just after changing to channel 9 and 20 MHz that I did earlier today, I got like 46/30. But still far away from 100/100. But now as I said 12/6. Just one hour ago I got max 2mbps .... so it's SO UNSTABLE.

When I use 5GHz on my iPhone in second floor I get 40-50/20. In first floor like 100/100.

When connected to router with cable the ping is still 15 ms, but connection 100/100 mbps.

So it seems like 2.4GHz is fucked up somehow?
Could someone please help me? My energy is like empty. I've tried everything.

QoS is disabled. I have tried activate and deactivate jumbo and NAT. No difference.
Firmwire is the newest.
IPv6 disabled.



Sorry for my bad english, it is not my foreign language.
I use D-Link DWA-140 RangeBooster USB that is connected to my computer for wifi. It worked very good with all the previous routers.

Please help me figure out this. :(

How many devices are connected? Try to change the channel of 2.4ghz to AUTO and set channel of 5ghz to 34. It's so strange. Maybe you will need to contact to techical support.

Good luck.
