I currently have a network setup represented in concept by the picture below. NOTE that there is only a SINGLE wireless bridge. Ignore the RED. The connection is 54Mbp/s using Netgear WG302's. As it turns out, all speedtesting indicates that although it operates with the 54Mbp/s protocol, actual best speeds are about 10-15Mbps. There is good line of sight. I just suspect that with earlier chipsets or with the power of the embedded processor, it cannot perform faster. 15Mbps is fine for internet browsing, but awful for file movement. I would like to add a second bridge. Shown in red. I understand that the second bridge will not speed up transfers for ONE computer... but hopefully will mean that if a second computer tries to access the internet while the other computer is transferring files, it wont be blocked due to all bandwidth being allocated to the file transfer. This is actually really important because across the buildings we also have ISDN over IP, ie telephone. If someone is on the phone and someone else does a file transfer the line can go down due to loss of bandwidth. Can i do this, or is there now a network "loop" that will cause problems with DHCP and LAN routing, and maybe even bring the network down?
