Hi all
I've been playing around with the Tx power for a while, because when I try to copy files from/to my android device and the HDD connected to my R7000, I found the speeds to be very very slow.
For example: a simple copy from my HDD to my Android device on 5Ghz channel, I get about 1.2MBps... that's unusually slow.
I was thinking that maybe an increase in Tx power will help a bit, but I didn't find meaningful evidence for it.
I used WiFi Analyser app, to measure dB of 5Ghz, and didn't find a slight increase in dB or transfer speeds.
So, either my router is misconfigured to utilise the bandwidth (I think it is) or my Tx power is not configured correctly.
I'm using Kong build from 10-MARCH
5Ghz is set to VHT80 + 166 channel and Upper Upper.
Tx Power is 120mW

im using R6300V2 and iPhone 6 Plus, i get around 15-16MB/S from usb 3 attached HDD, or 30-33MB/S from NAS connected to Lan of R6300V2.
did you try connecting to Lan ports using a PC and do a transfer? it might be related to USB/HDD rather than wireless.

I don't have LAN enabled storage device. Only USB or eSata.
In my case, I have a USB device connected to the USB3.0 port which is slightly better but not by a great deal. Problem remains... this is very disturbing.
I dont' know if it's my client (mobile) or the router settings.
I wouldn't mind if someone could remote to my router and figure it out...

i understand, however, 1MB/S is really slow, many years back i used to get 5MB/S on older hardware (E3000).
my question remains, did you try to connect a PC to lan port of R7000 and transfer a file from R7000 USB HDD to PC?
Hi gil80, FYR, below is some test results on my R7000 with stock firmware on an USB 2.0 external hard drive testing with Lan Speed Test (Lite) from TotuSoft (using testing file size of 1000MB).
With the external hard drive connected directly to a PC, I can get 19MB/s write and 30MB/s read.
With the external hard drive connected to R7000 USB 2.0 port, on 5G N HT20 with max 216M wifi link on PC (my PC has a wifi adaptor with 3 antennas), I can get 10MB/s write and 14MB/s read.
When I change wifi from HT20 to HT40 with max 450M wifi link, I can get 13MB/s write and 18MB/s read.
Some more info after more testing.
Using LAN Speed Test (lite) on wired PC and wireless PC with HDD on USB 2 and formatted EXT3:
see attached image. results in MBps.
So it seems that something to do with my mobile and router config that is not working right.
I have an AC1450 with a 5tb usb3 drive attached, and I've seen 20+mbps read speeds from my phone on 5ghz AC. My laptop on the other hand (yoga 11s) has a crap proprietary 2.4ghz single band WiFi card that doesn't roam between APs and has no roaming settings. I love the computer except for that, but transfers are often painfully slow, between 1 and 2 mbps, and I have to switch WiFi off and back on when I go to a different floor in my house. I ended up getting a usb3 hub with an Ethernet port for when I need to transfer anything of substnacial size.
As your numbers from your PC tests seem reasonable, I'd say its your phone. It seems like our scenarios are flipped.
That being said, I have solid range and minimal tx errors with 2.4ghz set to 316mw and 5ghz at 500mw. The radios stay a bit cooler than using auto as well.

Yeah, those are really high values that aren't going to do anything other than potentially damage the radios and cause errors/problems... _________________ Deployed Routers:
