Title: Some tips in conf to boost wifi
Post by: kazary on September 19, 2015, 12:49:14 PM
Hi!

The router is in a central room  of the apartment (less than 90mē, ie it is not big). One of the rooms - which is a short distance from the router, with 3 wall from distance - suffers from a weak signal. I can hardly watch one video at 480p on Youtube sometimes. And the contracted speed is 20mb.

In this room, my laptop, iPad, Moto X connect to a wifi with low signal. At least the iPad can sometimes see the 5Ghz network.

What can I do to improve the signal by changing the settings? Without having to resort to answers like buying a repeater  :-\, since I bought this router thinking it would not suffer this problem anymore (my previous router was a Linksys E2500).  DD-WRT firmwire can at least increase the Tx Power.

Model: DIR-850L A1
Firmware: 1.12WW Fri 26 Sep 2014
Wireless card: Intel Centrino 6230

Thanks for any tip!

Not sure if this helps, but the 5GHz signal will have half the penetration assuming that it's using the same signal strength as the 2.4GHz signal.   If you use different SSIDs on different bands maybe force the distant devices to use the 2.4GHz signal and the closer devices to use the 5GHz signal? 

The 2.4GHz signal can be optimized too.  The channels overlap, so pick 1, 6, or 11.  3 overlaps with 1, 2, 3, 4, 5, 6 and 7 IIRC.   And as you can see, your software recommends 11.

So without any ability to boost the signal, this might provide some relief.

* Channel 11.
* 5GHz where your devices support it and are located closely to the router.
* 2.4GHz for your more distant devices.

Different SSIDs allow you to control which devices are picking what channels.

5GHz should be your first choice since the spectrum is more open, but you may need to juggle, unfortunately.  At least if you force your stuff to 5GHz where it's close, it's removing those devices from the 2.4GHz spectrum, leaving more of that open for the more distance devices.
