A very good price on the 4 pack, if you're looking for a well priced solution. I think most compare these against the S7, especially as we've seen fair pricing on those recently. That said, the M4s here are a fair bit cheaper with this deal, so they'll likely make sense for a lot of people, that don't need the extra features of the S7.

Here's the comparison list for the two models.

Delivery is free

    Just FYI on a couple of cons:

    They don't work when the Internet is down, so the whole LAN would also go down.

    If set to Access Point Mode - in the event of a network outage or power outage, currently they'd come back on still looking to assign IP addresses and would 'fight' with the main router. The only solution is to power down all of the units and main router, then router back on and wait a while before turning the M4s back on.

    Well of course they won't work when internet is down.

    If you have a power outage wait for the main router to come back on then unplug and plug back in the ethernet cable to the first Deco from your main router and it'll will sort itself out (owner of deco M9s)

    What speeds can we get with these on 5 GHz?
    BucketMan's avatar
    Okay I just tested mine.

    One machine connected by ethernet to a second access point in AP mode.
    And a Chromebook running Crostini / Linux layer over wireless ac. Using iperf3.

    Next to the access point I got close to 400 Mbits/second.

    Through a chimney stack in the bathroom next door I got 80 Mbits/second.

    Then connecting to the primary AP with the laptop. About 170Mbits/second through one brick wall. The second AP is on the second floor through a wall/floor. So this is using the wireless interconnection between access points.

    Which isn't that bad.

    I'm not sure if the Linux emulation/VM will be bad on network performance or not, that's all I had at hand.

    Of course that's all local traffic. My WAN speed isn't that fast, so haven't been able to really test these.

    These are great for big houses with thick walls, easy to set up and easy to manage parental controls on a per device setup.
    slipd's avatar
    That's worth knowing. I've tried Parental Controls of some of TP-Link's lower-end router kit and it's been sketchy at best...

    I have the Tp-link AXE75, would these work with OneMesh?
    BucketMan's avatar
    No. Tp link seem to have two mesh techs. One mesh and deco. Not if you want a cohesive mesh with your existing router.

    Price increased. Still this price on eBay if you hurry. Just ordered.

    Seems to be great price for the kit.
    How do these compare to BT whole home full size disks ..?
  9. Noteddie's avatar
    Having had a few mech networks, I would say these are easy to setup and control. Well worth the money for 4

    heya, how's Ur day gone? tonight Im making pizzas for my parents and my bro and his bitch wife for by my birthday family celebration over at their house, I gotta get over there for 7ish to prepare and I was just thinking about getting stuff - I got 50, could've 9mm.9k.99m9.⁹9 we get some more from Clay? Did u work out what ti do wiv your big purchase yet?
  11. BucketMan's avatar
    This is a good price. Note though that Tp Link have a back door into your network, and it must be a reverse tunnel, as my pair sits behind a router. That's my main gripe. Performance has been fine. And the spare ethernet slots on them are useful if you have janky wireless on your PC. Mine are in AP mode. I did read at one point people were getting high CPU loads in router mode. Not sure if that bug was fixed.

    Sorry what? What does that mean?

    One of the best things I ever bought. They're brilliant

    Does anyone know if they work OK with Sky Q including multi-room?
    paulsl's avatar
    I have my Sky Q main box connected directly to my router as Sky engineer advised mesh connection can be problematic.
  14. BargainHunterUK1's avatar
    The TP link products are great, but beware, they struggle with IOT - namely their own light bulbs... my bulbs keep resetting and I was advised this was a problem with their mesh and to get the very expensive XE75 mesh units to support the bulbs..... not ideal and am looking at a workaround, but aside from that they are great (edited)

    Any use? You can create a ‘IOT Network’ that looks like it works only on 2.4 gig specifically for IOT devices

    Excuse my ignorance. Can these be wired to each other or do they only connect wirelessly?
    sasuke0's avatar
    Can be wireless or wired
  16. pannan's avatar
    Kinda useless depending where your main router is situated as you can't daisy chain them
    dreamypuma's avatar
    But still infinitely better than most ISP routers. Wired Backhaul is not critical, but preferable.

    If location prevents this, then powerlines would provide a similar effect. If none on these work for your location then it probably not the solution for you.

    Still a great product (particularly at this price) for those it works for. (edited)
