Customer Comments

  • I can’t find the pinout for the 10 pin serial interface. Neither here or on Roving Networks site. Does anyone have it?

  • I want to use my WRT54GL to control and monitor some devices because there is a significant power savings with the router verses a full blown computer. I would like to control and monitor things like the fish tank, cat food dispenser, humidor, etc.
    Once I get it connected, does it work like the other wireless offerings? Basically a character on the TX line of this would appear as an identical character (with the appropriate software) in a tty on the router?

  • This is a neat device…I can see a lot of uses. I am a bit confused though…can it connect to a wireless router or does IT become a wireless router?
    For example, I’d like to be able to have this device bring up a list of detected networks and then connect to one of them. Then it would attempt to connect to my custom server running on a PC on the network. I could potentially have many embedded devices connect to the same server, and the server could control them all.
    Or…does the device become an “available network” when your PC does a scan, and then you have to connect to it that way? I can’t imagine it would work that way, but I didn’t see a way to query for a list of available networks in the docs.

  • Datasheet says it supports WEP128, WPA-PSK, and WPA2-PSK (TKIP and AES).

  • Any chance of telling us what form of encryption this supports?
    Wep? WPA? WPA2? WPA Enterprise?

  • All the documentation says this is a 802.11b device, whereas this page says its an ‘n’ device? Which is it? :o
