Linksys e6350 v3 - Wifi very slow - ethernet ok

hello !
I'm new with Openwrt, I buy Linksys E6350 V3

  • I installed OpenWrt 19.07
  • my Ethernet connection is ok ( around 45Mbps) but not very stable
  • but my wifi was slow 0.2Mbps :frowning:

I search on this forum and on internet, I try some changes

  • channel not used

but don't find good result

If someone have ideal..

thank !

Which version of 19.07 ?
Have you changed the Country code from default in Wifi settings?

Which wifi band are you using? 2.4 or 5
Is the other wifi band affected?

Are all wifi devices affected or just one device?

Is 0.2 mbps for both download and upload speeds in tests ?

fwiw, I've witnessed 0.2 mbps downlink and 54 mbps uplink with one legacy 802.11g wifi device (2.4 GHz) last year as reported by LuCI.

thanks to help

OpenWrt 19.07.4 r11208-ce6496d796

yes it's "FR"

I use 2.4 but twice are enable


all devices (android phones and laptop)

I launch speed test again and it's
0.04 mbps for download and 5.13 mbps for upload like each test

(with ethernet 49.4mbps / 5.19mbps)
(and connect direct on SFRbox wifi 52.3 mbps / 5.16mbps)

linksys is connect to box with ethernet

I have one EA6350 v3 as openvpn client on 19.07.4.

default country code.

I tested a laptop with Atheros AR5B22 802.11n wifi card. I measured 25 mbps download speed through VPN over 2.4 and 5 GHz wifi.

I also changed the country code to FR for 2.4 GHz. I still see 25 mbps.

What are the link speeds reported in LuCI > Status > Overview > Associated Stations for connected wifi devices? This is where I have seen 0.2 mbps instead of 54 mbps downlink speed with an old 802.11g device placed next to the router last year.

I do not know the SFR box. What is its LAN IP ?
If EA6350 is operating as a 'router' and WAN port from EA6350 is wired to LAN port of SFR box, what is LAN IP of EA6350 ?

65.0 Mbit/s, 20 MHz, MCS 7
26.0 Mbit/s, 20 MHz, MCS 3

65.0 Mbit/s, 20 MHz, MCS 7
6.5 Mbit/s, 20 MHz, MCS 0

1.0 Mbit/s, 20 MHz
26.0 Mbit/s, 20 MHz, MCS 3

it's not stable..

I used this speed test for compare :

SFR is an Internet Service Provider and SFRbox is the modem

Box is
EA6350 is connect to box on and it's for the LAN

I use

Only other thought is I deleted WAN6 interface on my EA6350. I only use IPv4.

Update: I disabled the openvpn client and ran speed test via 2.4 GHz. It returned 45mbps down which is what I'd expect from my ISP.

thank to try, nothing better without WAN6

wifi is unusable :frowning:

Were speeds ok when EA6350 was using Linksys stock firmware?

hi all , so I try stock firmware and same probleme, I contact Linksys GREAT SAV !

Linksys call me (I ask french guy) and we try lots of things but nothing change.. :confused:

=> wifi may broken

Hardware is second hand old, and more than 2 years old so it can't replace it..

ma bad

Linksys SAV is free and nice..

thanks you
