Experiment over? DLM it seems didnt like me staying too far below 6db, line just got banded.

[Alex Atkin UK]

Shame, but I admit I am kinda waiting to see if that happens here.  I really wouldn't have thought it would do so with low errors though, but its probably more tetchy with an interleaved line?

I am still going to be using it for an AP, this thing has much better wifi without ugly antennae's.  My noise margin was going as low as 2.2db, so I think that freaked DLM out.  The last time I got banded it also occurred on a sub 4b noise margin.

That's interesting as I found the HH5A has awful WiFi, but then I immediately gave up on it when I realised it became CPU bound accessing the LAN getting half the performance on 5Ghz that it should do, I didn't really test the range.   That's still well above 80Mbit mind you, so for Internet use only its probably indeed fine.

Since i can see Home Hub 5A been used, I Just thought ill add the fritzbox 7530 on OpenWrt with VDSL 2 working (When i did) but swap it due to my local cabinet been Hauwei but this was my stats on TalkTalk (none wholesale)

Edit
Forgot to mention that is not in the OpenWRT snapshot/release, you have to compile from janh's github https://github.com/janh/openwrt

That's interesting as I found the HH5A has awful WiFi, but then I immediately gave up on it when I realised it became CPU bound accessing the LAN getting half the performance on 5Ghz that it should do, I didn't really test the range.   That's still well above 80Mbit mind you, so for Internet use only its probably indeed fine.

At close range its similar to the C7, but through wall's its in a different league.

I only use wifi for internet or light LAN use, if I need it for fast LAN, then I always use ethernet.

The C7 to my firestick was about 5-10mbit downstream, with dongle hanging on a hdmi extender, with it in TV directly about 2mbit/sec. (upstream was fine).  On the HH5A it maxes the line rate even with the HH5A in same place as C7.  Not sure what these external antennae's are doing.  The C7 was also better than the Asus AC68 it replaced.  The devices get better as they progressively get cheaper.

[Alex Atkin UK]

That makes sense, as I only compared it to the C7 in close range, I pretty much never need to use WiFi outside of the room my AP is in.

It does make sense though, there are losses in the antenna pigtails and connectors so internal antennas especially when etched or soldered on the PCB directly will theoretically be both a stronger signal and more sensitive for reception.

A friend of mine has my old WDR3600 in his loft and the signal is completely gone on the ground floor so there's a HH5B there doubling as a switch.  In comparison the Virgin Superhub DID reach the ground floor but was too weak to be very usable, so we put it in bridge mode so the 3600 could apply AQM.

I assume its all been working as I haven't checked on the setup in years.  All I know is with VM upgrades he has hit the limit of the 3600 CPU now so it bottlenecks.  Was going to replace it with the C7 but then pandemic.  Probably end up with the Fritzbox 7530 instead at some point, if its ever safe for me to do it.

If your talking about the tp-link's then the 3600 only has a single core @ 560mhz and the c7 is singe core @ 720mhz. The HH5A is a dual core but i believe is something to do wit that CPU is limited on that device! I believe the LANs/WiFI are limited to 150Mb max! Shame really but thats Lantiq/intel i guess 

Take a look at Bill888, He has a graph for speeds however not sure on the 21.02.x builds of openwrt yet
https://forum.openwrt.org/t/18-06-4-speed-fix-for-bt-homehub-5a/23643/23

Good news thought, The Fritzbox 7530 is a quad core armv7 but since is flat and have no antenna's, The WiFI range will be a issue but for switch or routing wise would be pretty solid  also remember there is a broadcom AX 7530! https://en.avm.de/products/fritzbox/fritzbox-7530-ax/technical-specifications/ same stuff but with WiFi 6/AX

[Chrysalis]

I should add I never tested the HH5A for LAN performance, so when I say same as C7 close range, I meant internet throughput.

The 7530 might be good on range, as currently no antennae's wins for me on range.

[Alex Atkin UK]

Yeah the 7530 is much faster WiFi to LAN (the HH5A is heavily CPU bottlenecked) but both I'd expect to match on Internet.

also remember there is a broadcom AX 7530! https://en.avm.de/products/fritzbox/fritzbox-7530-ax/technical-specifications/ same stuff but with WiFi 6/AX

Problems is Broadcom = no OpenWRT.   FritzOS is great for the average person, but as a techie I hated it.

the HH5A indeed is heavily CPU bottlenecked even though it has a dual core CPU lol

Few BCM devices are supported via OpenWrt https://downloads.openwrt.org/snapshots/targets/bcm63xx/smp but limited to either there WiFi drivers such as the B43 drivers what isn't open sauced,

Sky SR102 (Back) https://downloads.openwrt.org/snapshots/targets/bcm63xx/smp/openwrt-bcm63xx-smp-sky_sr102-squashfs-cfe.bin is supported based on BCM63xx however no DSL/WiFI such due to no open source drivers, however the SR102 takes an mini pci express wifi card so you can get atheros card and install the drivers inside the Luci webinterface for driver support.

FritzOS is great but settings up thinkbroadnand's and f8lure's BQM isn't good, only if you like seeing your Broadband in Red
