Just trying to make sense of the range...
TL-MR11U (TL-MR3040) - USB port for WWAN dongles; Internal battery; Micro-USB-powered; OpenWrt support
TL-MR3020 - USB port for WWAN dongles; Dedicated switch for different operation modes; Mini-USB-powered; OpenWrt support
TL-WR800N - 2x2 interface (300Mbps operation); AC-powered
TL-WR720N - 2 WAN/LAN ports; USB port for WWAN dongles or charging devices; Dedicated switch for different operation modes; Micro-USB/AC-powered; OpenWrt support?
TL-WR710N - 2 WAN/LAN ports; USB port for charging devices; AC-powered
TL-WR703N - USB port for WWAN dongles; Micro-USB-powered; OpenWrt support
TL-WR702N (US) - Mini-USB-powered
TL-WR700N (US) - AC-powered
All of them have at least one WAN/LAN port
Some of the models have only 2MB flash. OpenWrt in general requires 4MB flash.
702N and 703N have smaller chassis than the rest of the models. (See the the relative size of the LAN port and the chassis.)
TL-MR11U / TL-MR3040
Corrections are welcome!
