Many have left technical/usability reviews of this item, and that's excellent so I'll not repeat what's been said. I also try to look for reviewer's experiences of the whole process before making the leap, being familiar only with equipment I've used for many years. I didn't appreciate how good/economical the mobile data service has rapidly become. I'll try to hopefully pass some useful info on, and add to others experiences.I've been humming and hawing whether to get one of these routers for a few months now - the cost may have been a big gamble with no guarantees; however, the usual arrangement of putting up with a sluglike broadband service, poorly maintained lines/equipment, waiting days for engineers, slow speeds when the kids are on Netflix, Prime etc.. was wearing thin. Living rurally I'm lucky to get 4-5 Gbits.The last of three engineers to visit in four weeks, attempting to resolve the same incoming line issue, suggested I look at coming off landline broadband. I noted (speaking to numerous engineers - therein lies a story! - from BT..Sorry 'Open Reach'), that every time I floated the govt promise that everyone -100%- would have fibre (1 Gbit) by 2025 they collapsed on the floor laughing. I already suspected the cost of laying line for rural properties would be enormous, and therefore wasn't too surprised. The promise is recently downsized to 85%. That's clearly minus 15% rural areas. No shock there, and there's still loads of time to reassess further!There is the notion that some providers would love you to accept inflated promises thereby making you reluctant to jump ship because a fantastic service is really (honestly!) just coming over the horizon. Clearly that is not the case.So quickly googling I looked at coverage and type - 4g, 5g etc - for my area. My son is on O2, wife on Vodafone, me on Tesco, and using those phones I checked data reception across my home. Result 15 - 30 mbits (4G). Great! Decent reception confirmed - tick.Ordered the TP Link mobile router. Put in micro sim from my phone. ID (ssid) came up on my Fire so entered passkey (from rear of modem) and connected. Opened a browser and searched for 'speed checkers'. Average from 6 checkers came in at 19 Mbits download and 17 upload. Previous fixed line gave me 5Mbits on a good day and less than 1Mbit upload.I now have an unlimited data sim from O2 (comes as mini sim - no fuss, clicks in as normal). I already have homeplugs (6 x tp link PA211 from Amazon) and they work fine with this unit. No changes are needed. I also already have two wifi extenders - bog standard under £20 models circa 2018 (my house is over 20m by 7m x 2 floors). They happily link to the router just the same as with a home hub or other line router, and in practice they perform much better than with HH5. The home plugs ( + 'wired' connections) measure at 20-25 Mbits, wifi fluctuates from 20+ down to around 15Mbits. Coverage is now full; upstairs and downstairs.Now I know some with 40+ mbits will laugh at those figures but, when 5 mbits was the best I was getting, three times that speed as a MINIMUM is a real result.Like all routers I've ever had in the last two decades you can interface with it using a browser and entering http://192.168.1.1/, so set up is easy. This unit instantly recognised both my Sims. Set up is really just confirming info and "dotting the i's" as wifi was up and running before reaching the set up, as without it access isn't possible anyway if you're not 'wired'. The interface has monitioring and limitation facilities. My unit has detachable antennas.The monthly cost of our old landline package was nearly twice that of a £33 pound/p/m unlimited sim so I'm already ahead, the unit will be paid for in a few months. You can keep your basic email or pay a few quid for a premium email with BT if your worried about losing, or the kerfuffle of changing, your email when terminating your broadband. I suspect other providers will be similar. The loss of a landline, and all the marketing/nuisance calls that came with it, caused very little pain. Mobile minutes are now very cheap.In conclusion I've vastly improved my internet service, almost cut my costs in half and have no more concerns over the age, upkeep, condition or 'committment' of the previous equipment/provider. I'm loath to use the classic 'I wish I'd done it ages ago' but it applies. Mobile internet is a winner and the only real alternative for upgrading in poorly serviced areas so I really hope this unit continues to perform.Simple and easy to set up - Go for it!

I bought this TP Link TL-MR6400 as a temporary solution while being in between fixed-line broadband providers, but from an economical point and the quality and features of this Router, I will not go back to fixed-line broadband any time soon.The Router has 4 Ethernet connections and can handle 32 devices connected via WiFi, this is enough for us as we usually use WiFi and have only 2 devices hard wired to the Router, both Solar Battery System and our Video Surveilance System work best with fixed IP addresses assigned to their MAC address.It’s very easy to set up the Router to do exactly what you want it to do; for details on full features like Firewall, VPN, Channel Forwarding, Parental Control, Guest Network, Data limit notification, Whitelist, Blacklist, etc etc please do check the User Guide PDF which Amazon.co.uk has available in the “Product Details”This Router offers many features you will not find on any consumer products but on professional equipment only, yet you won’t need a CCNA to setup your Router at all. From my point of view, the User Interface is nothing short of excellent and I think even a layman will be able to do a full setup -with all bells and whistles- like a pro.I placed a SIM card (2nd smallest setting “Micro”) into the Router, connected my computer via Ethernet cable, and logged in to the router. After updating the APN settings with what I found for my mobile phone service’s mobile internet settings, I just registered the 2 MAC addresses for reserved IP addresses, left the WiFi channel on automatic, changed WiFi network name and password and all our devices in the house were good to go. I have rarely seen a switch going that smoothly.The benefits of having a SIM card Router are, you only need a power socket and therefore it can be placed almost anywhere in the house, and there is also absolutely no hassle if ever moving house.The signal I receive with my SIM card gives currently 35MB/Sec Download, 12MB/Sec Upload, this is sufficient speed to watch a 4K movie on our Amazon Fire TV Cube and at the same time a Youtube video on another device, we even threw in a Skype Video conference for good measure. No lag, no interruptions, no issues at all. This all on a mobile internet connection? I’m seriously impressed! But I am from a generation that used acoustic coupler and speeds of 600 BAUD on dial-up.If you have found my review useful, I would be grateful if you would consider clicking the helpful button below, thank you.PS.My thanks to Vodafone Ireland. Your policy of existing, loyal customers being charged 50€ per month while new customers pay only 30€ for 12 months (on a new 12-month contract), is forcing customers to be not loyal and switch provider. You geniuses managed to burn at least this bridge, as I switched to a 7.99€ per month SIM card offering 100GB Data and I will not be coming back, ever. Let’s call it out: this Router is paid for within 3 months and then I’ll be constantly saving 22€ monthly compared even to your new customer deal. No more hassle of moving provider or trying to persuade you to appreciate loyal customers while being told to be grateful that I have a 10€ discount and pay only 40€ per month. Thanks for making my decision that easy, especially if there are great Routers like this TP-Link available - compared to your outdated and meager Huawei HG658c, on which you also frequently erased my settings via remote access.Several friends will finish their contract with you soon and they were all impressed with the Router and my monthly costs, it seems you just lost yourself a few more cash cows… continue to promote customer dis-loyalty. Bye-bye​!
