I’ll start by saying up front, I’ve no idea what I’m talking about but here goes.
We have an ASUS mesh system but we’re pretty sure one of the units has a problem so we either need to replace it with another Asus or change to another mesh system.
Can any of you teccy folk recommend a replacement system please, not massively expensive but not cheap junk. OH is going round in circles and I’m about as much help as a chocolate teapot. 
I can’t advise on the technological specifics (others will be along soon to to help with that) but I have had a Netgear RBK50 Orbi system for a number of years and it’s operated flawlessly.
The main unit is in the living room next to the internet router and the secondary box sits on my desk at the other end of the bungalow and picks up and retransmits the signal.
I can stream 4K TV with it (via the second remote unit) with no problems.
This is the kit I bought in 2020 -

No doubt there are more sophisticated and speedier ones available now but that’s what I can recommend from personal experience.
Andy, OH, has been looking at the RBE 773, something to do with 3 units as opposed to 2?, I’ll be honest I’m just passing on info’ and I should have said our internet speed is 10 mbs max!, in reality we get somewhere between 6 & 10!
Ok that’s a much newer and more powerful system than the one I have - and also a lot more expensive!
Could be good if you want future-proofing, but if you are only getting 10 MBps, then a) your internet provider needs a slap with a wet fish and b) pretty much any wifi setup would be quick enough!
(For reference, my internet connection here (Surrey UK) is 70 Mbps down / 15 MBps up, over a copper wire connection (fibre at the cabinet), and by no means state of the art, but sufficient for my needs).
We use TPLink mesh Wi-Fi at home and have 2 units, one that plugs into the Livebox via Cat6 network cable, and the other that connects via Wi-Fi to the one connected to the router. It works pretty well most of the time and covers all of the house and even some of the garden around. Certainly better than the Livebox coverage by itself.
The TP Link Deco Mesh system is pretty good considering that you can get 3 nodes for €120 or so.
The trick is match their speed to that of your current broadband speed. No point buying the pricy 1Gb/s stuff if you only get 50Mb/s into your house.
I’ve not played with the latest Liveboxes, but the 4 and 5 had terrible WiFi performance.
How do you know that one of your units is not working. Have you had a look at the dashboard of your app?
Also, if you’re only getting 10Mbs on a fibre then I would suggest that there may be other problems.

Yogesh
Apologies to you all because I should have said, we’re not on fiber, the Openreach cabinet is less than 500m from our house but in their wisdom they decided it was too expensive to run it up the road, so about 20 homes have rubbish internet.
Chris, he is future proofing as Openreach say we’ll have Hyper fast broadband before July 26, thanks to our now MP Tim Farron.
Yogesh, he’s run so many diagnostic test it’s driven me nuts! . Last week he replaced the cat5 cable with cat7, incase the cable was flaky, existing Ethernet cables all changed to cat7. Yesterday he shut the whole system down and reset, he did a factory reset on the Asus units and connected them in turn and ran diagnostics on each. One unit was consistent but the other kept giving fluctuating speeds and kind of pausing briefly.
Hopefully what I’ve written makes sense to you all?
Glad to hear that Opentrench are sorting you out!
But do they mean July 26 2025 or 2028? 
And Tim Farron is a good bloke. We have (Sir) Jeremy Hunt 
thanks to constituency boundary changes.
Although since Hunt came very close to losing his seat last time and is no longer in Government he has gone all Eager Beaver on local issues to ingratiate himself with the electorate. 
As for the future-proofing, unless you have a house full of teenagers who all need to watch different TV shows and play online games simultaneously, as @NotALot mentioned you may not need the absolute latest and greatest wifi kit.
My five year old Netgear setup does the biz with two of us in the house.
I think we guessed from the internet speed you quoted 
Tim’s a great guy, he raised our problem in ‘the house’ and after 4 years we’re getting there, we did have Barn lined up 2 years ago and just before they were ready to do the work, funding was pulled. We’ve had a long wait but earlier this year Fibrous appeared the shortly after OR said we’d have fiber by July 2026, prefer OR as we can choose internet provider, not so with the other lot.
As to the mesh, all I can say is Andy loves his toys! He already has 1 net gear that runs external internet , he needs this for the solar thingy and for his music, but he’d like opinions from real users and I told him a lot of you guys know your stuff,(I’m a creep)
Update, we’ve finally think we found out why the Asus unit is faulty. We had a very slight leak on a pipe in the bathroom above the room the Asus is in, we only knew when it dumped the water that had been building up. I’m pretty certain the Asus ended up sat in a puddle!
Up shot is, he’s been happy with them and, thanks to you guys pointing out we don’t have a need for anything more powerful and never will, he’s decided to buy a pack of 2 Asus, way cheaper than anything he’s been looking at. As we only need 1 he’ll have 1 as a back up if anything goes wrong with the other one.
I owe you all drink 
, no more talk about mesh……….until he sets the new one up!
Hi. New to the forum.
All the ‘new’ systems are more to be ‘wifi’ repeaters. For over 20 years in my Farmhouse (1m thick internal walls), I have used a combination of d-link 1Gbps powerline and Apple Airport products. Both are available still on the internet though the apple stuff is mainly eBay.
Starting at the router I install the pass through power line. I plug the router direct into the power line so the power is always on. The next powerline is strategically placed and using ethernet cables I connect to the apple unit. Using Apple’s Airport utility it will create another wifi hotspot using the same name as your router wifi. As you walk around your house your device will not know the difference and the transition is seamless. You can add as many powerlines as you need and as many Apple Airport extremes as you need. All Apple products will provide 1.3Ghz wifi. Extend as you need.
Powerlines can be purchased for a reasonable cost. Apple Airport products can be purchased for as little as £10 on eBay UK.
I have a 415m2 home and everywhere including the garden is covered at full strength. Total cost? £200 to date: at today’s prices.
Do you use anti surge power blocks, we had EDF spike our supply several times in succession and it fried the router. It also could have been that our line and neutral to the house were reversed at the time .
Thanks Brian and welcome to SF, I’m passing this onto my OH as it’s all gone over my head quicker than a bullet 
, I’m the least teccy person in the world in fact, I think I was a Luddite in a previous life
I do use anti surge units. As for ERDF I have started a local group that is putting ERDF and Enedis under pressure to explain why they are so poor at supply, and more importantly, why they expect us to go to our home insurers to pay for items their poor supply has caused to fail. In my instance, 4 TV’s in 12 years. Now the insurers refuse to cover the TV and I am left with a Darty special.
Keep us posted how that goes on. I lost a TV, router, and had an expensive repair bill for an inverter due to the spikes and subsequently finding out they reversed the phase and neutral.
I got paranoid about electricity supplies in France, surge protectors on everything important, I adopt the same attitude here much to my hubbys amusement.
It seems we have a couple of wifi dead spots in our house.
One is just above the router (which sits in the basement); the other is on the first floor.
I have a powerline system to link the router to the ground floor, which works well.
I’m wondering if having a mesh system to link the ground floor with the first floor would work.
Well every house is different, but yes it probably would. You might not need the powerline gadgets. I used to use Devolo powerline ones but they would drop the connection from time to time.
I have had a Netgear Orbi mesh wifi setup for six years and it has been flawless - the main box is next to the router in the living room and the secondary unit is in my bedroom/office at the far end of the bungalow.
I imagine that with all the new tech that has come along since then a current model would be super-whizzy.
Even with the 70mpbs copper cable broadband that we have I can stream 4K to a TV from the secondary box.
ETA: If in doubt get it from Amazon so if it doesn’t work you can send it back!
