Flint 2 (GL-MT6000) vs OpenWrt One vs R7800 Wi-Fi

I'm looking for the best WiFi possible today for my house, short of adding access points. My current r7800 is doing an acceptable job, but I get some moments when my teradici work from home connection is poor since upgrading to the current release. Before the software upgrade everything worked great.

I also dislike the 32 device limit of the ath10k-ct driver.

My hope is the mt76 drivers and wifi6 on the other routers would be a step up. I'll use an USB wifi6 adapter on my PC along with this router. Should I expect any difference in WiFi quality over the r7800 or is it just throwing money away?

I'd like to buy the OpenWrt One, but it looks like the the gl-mt6000 is a few bucks cheaper and would arrive earlier as of today in Canada. It looks like it'll be better in every way for me?

I love my MT6000. It does everything a home user wants (SQM, DoT DNS, ad block).

I own both a Flint 2 and an OpenWRT One.

The Flint 2 is has 1 2.5gbe WAN, 2.5gbe LAN, 4 1gbe LAN, roughly 2x more powerful CPU, 3x3 4x4 wireless, and more built-in storage 8GB.

The One only has 1 2.5gbe port and 1 1gbe port and 2x2 wireless, 256MB storage. But it has internal bays for an nvme SSD and the MikroBUS (e.g., for a LoRa radio or other interesting add-ins).

Both are fast and reliable, same RAM, but they are pretty different in the details.

For hands-off reliable home router use, the Flint 2 is probably a better choice. If you want to experiment with other uses like NAS, hook up a serial console, set up a backup Internet connection with an add-in card, or do development of OpenWRT itself, then The One has some unique benefits.

i had a r7800. i have a flint2. they don't even play the same game.

According to https://openwrt.org/toh/gl.inet/gl-mt6000 it is 4x4 not 3x3, so even better.

Also, my Flint 2 is fantastic. So happy with the choice.

Yes, you're correct, apologies for the error.

I have a Flint 2 - MT6000, and also the Beryl AX - MT3000 (same SoC on the OpenWrt One)

I highly recommend the Flint 2, it is really powerful, it can handle up to 800-900Mbps with SQM, the OpenVPN performance is great (around 240Mbps) and WireGuard even better (900Mbps). It is perfect if you wanna run AdGuard or Tailscale

I have a lot of things running on it and I feel like I’m not even taking the 70% of what it is capable to do. The range is solid. Go with that one you won’t regret it.

2x cores * 1.5x frequency = 3x

The OpenWrt One has a third antenna for Zero-wait DFS OpenWRT One only allows 2x2 MIMO 5GHz - #7 by castillofrancodamian
Not sure if the Flint 2 has this as well (?) - This suggests so https://wikidevi.wi-cat.ru/GL.iNet_GL-MT6000_(Flint_2)

3rd antenna isn't for ZW DFS. It's for BF on 5G. Maybe it's also improves RX, I didn't read whole docs.

mt7981 has 4.5 dB gain on 5G (3T1S) vs 2.9 dB gain on 2.4G (2T1S). BF ON vs BF OFF

mt7981 and mt7986 support only software SW ZW-DFS.

do you mean that this info is incorrect from https://docs.banana-pi.org/en/OpenWRT-One/BananaPi_OpenWRT-One#_hardware_spec ?
(sorry, not sure what BF or SW means here)

SW ZW-DFS is still ZW-DFS. The limitation is that it's only works on 36-64 channels and with BW 80/160.

mt7981 5G - 3Tx3R/2SSx2SS and no dedicated RX antenna for DFS
mt7916 5G - 2x2 + 1xDFS for HW ZW-DFS

UPD1 mt7981 and mt7986 have one radar detection device (rdd1).
mt7916 has rdd1 and rdd2 which is connected to dedicated RX-DFS antenna.

That's why mt7916 supports background radar detection and ZW-DFS on all channels and with all BW

UPD2 from mt7916 docs

An additional antenna boosts downlink performance via zero-wait DFS or MRC

So 3rd antenna on mt7981 should also improve RX speed.

I've got both, MT6000 as main router (running PPPOE, 1gig, December Snapshot) and R7800 (January snapshot) as AP..

As far as WIFI speed (WAN speed test) is concerned this is what I get:

R7800 = 600-650 Mpbs
MT6000 = 700-800 Mpbs

The R7800 is performing very well for a router of that age.

I have seen the MT600 do 900Mpbs, and it should be able to, however I have only seen this once or twice.. I am running a "tweaked" build for MT6000, so likely to be performing slightly better than the official firmware

I'm getting 1950mbps on mt7981 xD (1800mbps without overclocking CPU)

Sorry, I didnt mean to reply to your post.. I meant to reply to the OP, where he asked for feedback on R7800 and MT6000.

I've transitioned from caring about peak throughput to latency to now reliability and consistency, especially at range. The first items are effectively solved. OTOH I wanted colour changing smart bulbs on the outside of my house for Christmas, but even though my phone works fine there the signal wasn't strong enough to to use them. Any comments on how devices can help in that area?

Blockquote 3rd antenna isn't for ZW DFS. It's for BF on 5G. Maybe it's also improves RX, I didn't read whole docs.

I can't find what BF is. Can you explain?

so.. mt3000 here..

swapped 2.5 to be lan and 1 to be wan..

I'm a 300/30 (all that actually works where I live..)

any suggestions for packet steering and offloading on the chipset?

I cannot find any 'optimal' settings thread

Thank you in advance..

With 300/30 all you need is SQM or something like this.
