I use a TP-Link Deco X50-5G ax3000 whole home mesh WiFi 6 router from Lazada, coupled with an AIS 5G SIM. Ties in nicely with the rest of my Deco mesh.
I tested swisscom sim card and wingo swisscom 1st sim, and even their 2nd sim option with 5g internet upgrade and that was quicker than my copper via Sunrise at home. Now I get 500mbps over wifi on a bad day, and up to 800 on a good. Compared to AX6000 router with cable it's always 500 or less. Price difference 15 vs 50. Device is: TP-Link Deco X50-5G
Get a 4G/5G capable router. Buy your own data plan take it wherever you go. TP-link have some decent 4g/5g routers with wifi 6 standard. Or you could go with a gl.inet travel router
I got those cheapo deco x50 with wired backhaul, there are better ones. But the biggest difference I made was everything that doesn't move gets a cable. *everything*
My opinion. Asus aimesh. I have tried TP Link X50 but they spend more time offline than on. Orbi is superb however its too rigid. One router and 2 satellites doesnt like bridge mode or AP Mode. I moved to Asus with RT-BE92U as router and XD4 mini access points. Router mode, AP mode both work well. Versatility of being able to use most of their routers interchangeably as access points. There are downsides. Asus mesh doesnt seem to like IoT devices for smart home. Speakers, bulbs etc. Haven't tried Ubiquiti which a lot of people absolutely praise. If it was within my budget I would try it. Comes down to budget. If you can afford it. Ubiquiti by all accounts. Asus is a great option, Orbi is good if you use it as they want you to. TP Link for me is budget friendly but I think you would end up replacing it and spending again.
I have a 600mbps plan and i use a deco x50. Could deco x20 do the job, yes in paper. But the protocol (wifi 6) is not the only consideration. For deco x50 it has 2x2 mu-mimo which better handles wireless devices. I have wifi 5 device in theory should handle 600mbps but it reality it only handles 300mbps. In conclusion, you may need to know what are your devices and how many. Also what is the structure of the home (concrete or wood walls) if wireless backhaul would be enough or you need wired. If you dont want to think much. I suggest get be25 for future proofing. Deco x50 if your not gonna upgrade anytime soon.
