What owners say about the TP-Link TL-MR6400

Based on 179 owners sharing their experience in online comments

15%positive7%mixed78%negative

Owners value fast speeds and reliable service when compatible, but SIM and connection failures dominate.

What owners dislike

  • Some SIMs, such as Fastweb or O2, are not detected or listed in the carrier menu, so no connection starts.43
  • The router shows no internet even when the same SIM works in a phone, and owners often need a restart to get back online.22
  • Many owners find the same SIM is several times faster in a phone or hotspot, with the router often stuck on 3G or slow speeds.21
  • Weak signal means some owners get only 3G or two bars, with 4G missing on certain carriers even where the phone gets it.15
  • Connections often drop after minutes or hours, or after a power cut, and owners must restart the router to get online again.13
  • Some devices and apps fail, such as video streaming that will not play, a PlayStation 5 with no internet, or an Echo that misses Wi-Fi.9
  • The setup page often will not open while the router has no internet, and quick setup can be hard to follow.7
  • Antennas can sit loose, with one coming off in the hand, and a small pin inside the SIM slot has broken on some units.4
  • On weak or busy 4G, full HD live streams stutter and online gaming ping climbs to around 75 to 97, causing lag.3
  • The phone socket gives no line for a regular or cordless phone, so owners cannot use it for a landline call.3

Third-party reviews

What customers like about TP-Link TL-MR6400

  • Three LAN ports plus a WAN port for wired devices
  • Cat4 modem with download speeds up to 150 Mbps
  • Two detachable SMA antennas can be replaced if reception is weak
  • QoS, guest network and parental controls included
  • Connects up to 32 Wi-Fi devices
  • Setup through the Tether app or web interface

What customers don't like about TP-Link TL-MR6400

  • Wi-Fi 4 N300 on 2.4 GHz only
  • All Ethernet ports limited to 100 Mbps
  • No VPN server
  • Larger desktop unit at 250 g, less portable than pocket models
  • Cat4 modem caps mobile speed at 150 Mbps

Verdict

With three LAN ports and a fourth that doubles as WAN, the TL-MR6400 is a desktop 4G router rather than a pocket hotspot. A Cat4 modem takes a nano SIM and delivers up to 150 Mbps down. Wi-Fi is N300 on 2.4 GHz and serves up to 32 devices. The two detachable SMA antennas can be swapped for other LTE antennas if reception is weak. QoS, a guest network and parental controls cover the basics of home network control. All Ethernet ports are limited to 100 Mbps, and there is no VPN server. The SIM PIN can be entered in the Tether app or the web interface, and no other configuration is needed. It is a budget pick for homes with weak DSL and good 4G coverage.
