Model overview based on user reviews
The TP-LINK TL-MR3420 router is praised for its reliability and ease of setup, with users noting that it supports 3G modems, such as the 1550, excellently. It is described as a great adapter, especially after users experienced issues with other brands. The router's price-to-quality ratio is considered high, and it has been operating almost continuously for a year with minimal restarts, even in environments with frequent power outages. While the setup language is in English, which may be a minor inconvenience for some, the overall performance and stability make it a recommended choice.
Pros
Cons
I bought it after I returned the D-link 620 to the store, which after 5 hours of setup did not work with the 3G modem (1550). I immediately installed new firmware from the website. Everything works perfectly. The 3G modem 1550 supports it excellently. Setting up in English  Aleksandr: use TP-LINK TL-MR3420 week i recommend it should buy |
Very reliable. Operates almost around the clock for a year. Restarted it only about 2 times during all this time. No malfunctions despite constant power outages (new house - "its own" quirks). Quite easy to set up. Reliability no use TP-LINK TL-MR3420 month or more |
