Hi,
It it worth to install wrt in current status instead of tplink firmware which has no updates currently?
It is my primary router so nating and dhcp server is must have. Will be worse or better on owrt? I'm using a6 in wds bridging Mode also for extending wifi range.
Greetings!
This is iperf3 on C7 v2, measuring upload from my iphone. Using latest image, 80MHz 5GHz channel. 1GHz OC. Download is slightly slower (around 500Mbit/sec). I use them as dumb AP's so throughput is LAN to LAN only.
This is quite fantastic for 8 year old router and it will take long time for me to justify move to .ax
Do you have to change any default setting to get these speeds? I'm using TP-Link Archer C7 v5 and I never got its 5GHz speed to exceed 100 Mbps. Been using since 21.02 IIRC, and 802.11ac has always been the same. Nothing in the LuCi settings jumps out to me as the cause for this limit, and the previous replies here implies you all getting 300Mbps after firmware updates is even more confusing to me. Should I be enabling some software or hadrware offloading somewhere?
Just today I learned about forcing 40MHz channel width for bgn and that resulted on my 2.4GHz reaching almost 100Mbps. I hope there's a similar small change to get my 5GHz in order.
Make it 80mhz in 5ghz band.
I checked it again and it's already 80MHz. AFAIR, it was always 80MHz by default. And there's literally zero 5GHz signals in the vicinity, so there's no crowding, let alone any interference.
Are you doing a speedtest or iperf? It looks like you maybe limited by the 100mbps speed of the lan port?
Doing a speed test, I'll not be able to do iperf
anytime soon. But it's nothing to do with FE speeds, my router is all gigabit, and the upstream ISP interface is also gigabit (the service I'm supposed to get is 250Mbps). With a LAN connection, speed test easily goes above and beyond 100Mbps, so this is squarely a WiFi issue.
I have the same problem:

My ISP gives me 300 Mbps download and 30 Mbps upload.
In addition, when I choose in openwrt the frequency to be on auto mode, the network doesn't appear on my raspberry pi 4.
Is there any way to improve the download speed?
Enable offloading from firewall menu.
This is what I already did, it gave me 3-4 Mbps improvement, all the results are after I've enabled it.

I have two more SSIDs (on each frequency) which I removed for abbreviation. I've confirmed that both iperf3
and public speed test make no difference regardless of its enablement status.
I also tried to do iperf3
with Hurricane Electric's public iperf server, but the results are very inconsistent.
Software offloading is also enabled, but I didn't notice any difference.
This is what I'm getting (over 5 GHz, 80 MHz):

On another forum post I read that iperf3
needs the -R
flag to test download speed, otherwise it's uploading to the server. As per the manpages, it makes sense, so I reran with -R
and performance is worse than upload:

Closer to the public speed testing services results that I get, which basically peaks at 100Mbps.
On the same thread, it is mentioned 802.11n maxes out at PHY rate of 150 Mbps and, crucially, 100 Mbps of real world speed. That sounds exactly like the behavior I'm encountering, but I checked iw $DEV station dump
on both my laptop and router, and both shows 80MHz
and VHT-NSS 2
, so—as far as I understand—both devices are using the ac
and haven't fallen back n
. Which is good news, but I'm no closer to figuring out why I'm not getting the expected throughput.
It looks like you are using your router as the iperf server. That will eat up CPU and cause falsely low rates. Routers never generate network traffic from scratch.
Instead set up a wired computer to act as the iperf server, have the router as the in between, and then run the iperf client on your laptop. You should see full speed with the router acting like it is supposed to as the in between agent.
I've done as you asked, to almost identical (to router as server) results for both upload and download:

For the record, on wired connection, my real world speed goes beyond 200 Mbps (my service is for 250 Mbps).
Use two computers. One wired and one on WiFi. Run iperf3 on them, not on the router. C7 CPU is single core and is not powerful enough to run iperf3 internally.
That being said, if you use your C7 as combined router and AP (which is what common Joe calls "a router") you might be running out of CPU. I use my C7's as Access Points only and they are able to deliver around 400-500Mbit/sec in iperf3 "locally" (from WiFi to wired network), and that is with overclock from stock 720Mhz to 960Mhz and CPU pegged to 100%. Basically, stock C7 running OpenWRT will peg CPU to 100% just by moving packets from WiFi to Ethernet at 300Mbi/sec-ish, without routing.
The iperf in my last reply is as you and @ACwifidude asked me to do: iperf between wired and wireless device connected via the C7. And unlike your local iperf3
you mention, it's not going anywhere near 300 Mbps as you suggest. What settings do you have on your WiFi and how did you overclock?
Run iperf3 server on wired PC, connected to one of LAN ports on C7.
Run iperf3 client on iphone 7 or later and connect to C7 using 5GHz.
Configure OpenWRT for 80MHz channel, AC mode, WPA3.
If you cannot get at least 300Mbit/sec something is wrong.
