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!
Update August 2020. Changed to Vodafone Unlimited as 3 was getting very slow sometimes. Not just me but 2 others nearby had same issue and 3 were very unhelpful and lied multiple times on support calls. Told me the transmitter was being upgraded to 5G ... In the middle of the countryside with no houses within 200m of it? Yeah right.
We live in a rather underprivileged area as regards broadband. Despite being in London, we cannot yet get fibre broadband and BT "copper" broadband is limited to about 5mbps - and it's so unreliable, we are unable to reliably watch streaming films or sport.
So, I decided to try mobile broadband with this router. While we are surrounded by masts, only one is in direct line of sight but is fairly distant. So, after some experiments, I opted for a Poynting external 'directional' antenna. Having further experimented with a few provider SIMs, surprisingly, I found O2 to give by far the best service (I had assumed it would EE). Then, some fine tuning of the antenna was necessary to get the best signal and speeds.
I opted for a Tesco "SIM Only" unlimited data plan - being the most cost effective contract without hidden data limits (and it uses the O2 network).
This router itself is easy to setup and provides fast and consistent service. We consistently get 4G+ downloads of 70+ mbps. Indeed, in the evenings we get over 100mbps. Signal quality is 75%. That is excellent - 4G+ really works for us!
Another reason for getting this particular router is the capability of setting LTE bands manually. Given the number of masts in our area, there are unusual problems with reflected signals and, at certain times of the day, the router would automatically switch to another band. This not only slowed down downloads, it also interupted streaming viewing - particularly annoying during a football match.....
By manually setting the LTE bands (we use 40, 40), this problem was eliminated and we are rather chuffed.
With the 4x gigabit LAN ports, integration into our home network was easy. This allows access to our printers, home NAS, Blu-ray player, TVs and Humax YouView box. Connection to a DECO Mesh setup extends the router's fast 5GHz WiFi to everywhere in the house - including the all-important but distant kitchen!
As such, this particular router is ideal for our requirements and we are very pleased. It did take some time and thought to get the home environment set up correctly but, it was well worth it.
Goodbye BT, your high prices and poor service!
NOTE. If you require a 4G+ router that allows manual LTE band selection for aggregation, there aren't many available choices. This, IMHO, is the best at a reasonable price. However, beware, the V1 version of this router does NOT feature this functionality unless you get a special Beta version of the firmware from TP-Link support. So, opt for the V2 device - which is also a few pounds cheaper.
The V2 device also has the useful option for scheduled reboots. I set ours to reboot at 4am every other night. That can help in keeping things running smoothly.
I previously purchased a V1 of this router for my daughter's house. Like most users, she doesn't need the manual LTE band setting capability. Her router has now run without any issues or need of a reset for over 9 months. I wrote a separate review for that device.

You CANNOT attach external antennas to the latest version of this router. It previously came with detachable antennas but TP Link in their wisdom have made the latest ones so they can't be replaced. This is contrary to what it states on their website.
