I have a Motorola WR850G wireless router that I'm trying to use not as a typical router (DSL in, one wired and wireless home network out), but as a box that extends a subrange of my home net (192.168.1.x) to wireless clients with DHCP.
I know that a firmware like DD-WRT would likely work on this router, but before flashing DD-WRT onto the router, I would like to fully understand the original features it offers with its own firmware, version 6.1.4.
One thing I don't get:
In the LAN settings, I give the WR850G the IP 192.168.1.200 and tell it to offer DHCP addresses in the range from 192.168.1.201 to 192.168.1.254. This works. I can even ping a smartphone that got accepted via DHCP at 192.168.1.201 from another box inside of my wired home net.
Now, once I configure the WR850G as an Acess Point (the options are "Router" and "Access Point"), I lose access to the browser config interface. I know this has to happen once I give it another IP, but why does it seem to become inaccessible when it is put in the Access Point mode? Does it somehow lose its own assigned IP (192.168.1.200) when being put into this mode?
More generally put:
What does it do when I configure it as an access point, anyway? What is a wireless access point? The definition seems to be unclear.
Please excuse my noob-ness, I am still in the process of learning wireless networking, and sometimes the terminology is strange. For instance, on a wired network, a bridge is a box with two NICs, negotiating between two networks (e.g. 192.168.1.x and 10.0.0.x). On a wireless network, a bridge is something like two boxes with an antenna each, acting like a straight piece of CAT5 cable on the same subnet, without the connected boxes even noticing that they are using a piece of wireless network...
