TP-Link 1043 v3 WLAN too slow / config or new router recommendation

Hi,

I have the TP-Link TL-WR1043ND v2 with OpenWrt 19.07.4 r11208-ce6496d796 / LuCI openwrt-19.07 branch git-20.247.75781-0d0ab01.

I just did the Vodafone cable speed test and only get ~48Mbit/s download using WLAN (with client close to the router). Using LAN, I get the full 100Mbit/s download speed of my cable provider.

My wlan configuration is mode N with automatic channel und 20Mhz bandwidth.

Any idea what I can do to get more speed? Is it a problem of the current openwrt release? Can I improve my wireless configuration?

Or should I buy a new router? The 1043 is quite old, but so far I still haven't found a good replacement.

My requirements are:

  • good WLAN coverage / high tx power (>25 dBm) and good antennas
  • more than 4 LAN ports
  • enough RAM und fast enough for OpenVPN support (e.g. IPQ4...chipset)
  • <150€

I thought about the GL-MV1000W, since I like the GL.inet router, but it does not have enough LAN ports and not enough tx power.

Alternatives are the Netgear R7800 or Linksys WRT3200.

Any recommendations?

Just get the 7800. It is the most popular and supported high end router right now.

The wrt3200acm is great hardware, but the wifi drivers are buggy binary blobs with no chance of seeing fixes.

I'd say 1043 v2 (or v3) is good enough for 100mbps even with SQM.
To get more than 48mbps on wifi you need to force 40mhz channel https://openwrt.org/toh/tp-link/tl-wr841nd?s[]=noscan#stuck_at_130mbps_get_300mbps

Thanks. With noscan 1 and ht40 I get max 62mbps. What is the reason that I dont' get 100mbps? What is the limit?

CPU should not be the bottleneck, since load is ok with 0.2-0.3

single word - Interference - you can probably see at least a few neighbors' networks around.
The limit for a 300mbps link is around 200mbps for UDP traffic and for speedtests (TCP) you shouldn't get more than 150mbps - but that is under ideal conditions - no interference see here
