AI-generated summary
The TP-Link TL‑MR6400 is the kind of basic 4G router that’s great when you don’t need anything fancy. For £63.65 ex‑VAT, you’re basically buying a reliable “get us online” solution: for small offices, pop-up sites, warehouses with light usage, or as a backup WAN when the main broadband goes down. The 2.4GHz Wi‑Fi is fine for typical business tasks (email, web apps, basic VoIP) and it usually covers better than 5GHz in real-world, slightly messy building layouts. If your expectation is steady connectivity for day-to-day work rather than high throughput, it’s good value.
That said, I wouldn’t recommend it if you’re running lots of concurrent users, cloud video calls all day, or you care about fast wireless speeds across multiple rooms. It’s also not the best choice if you need heavy firewall/segmentation features or advanced network control—this is more “simple and functional” than “managed IT-grade.” If you’re placing it in a location with weak mobile signal, you’ll get limited results no matter what router you buy, so consider antenna placement (or an external antenna option, if you have one) before committing. Overall: solid budget buy for small sites and backup internet—just don’t expect it to behave like a £200+ business router.
