Trying to extend an existing wireless network (located on main floor of office building) to third floor offices.
Main floor wireless is set up using a 3Com OfficeConnect Wireless 11g Access Point. DHCP server is our SBS2003 server with address range for distribution 10.20.0.100 - 10.20.0.225
Configuration of this AP is as follows:-
IP Allocation Mode - Static IP manually specified
IP address 10.20.0.10
Subnet mask 255.255.0.0.
DHCP server is not enabled
Wireless networking enabled
SSID broadcasting enabled
WEP 128bit encryption enabled
Connection control - all wireless PCs can connect
Third floor is connected to main floor by ethernet cable running from third floor to switch in main floor server room. On third floor a D-Link swtch is connected to the network drop and a 3Com Wireless 7760 11a/b/g Access Point is plugged into the switch.
This AP is currently configured as a wireless repeater (its mac does not appear in the original APs client list). It is set to obtain its IP address automatically (current settings are IP 10.20.0.187, subnet 255.255.0.0., default gateway 10.20.0.1.
Wireless mode is 2.4GHz 11Mpbs (802.11b) / 54Mpbs (802.11g) Static SSID specified as ourwireless (specified by choosing from Site Survey); Security and Shared Key set to match original AP).
When testing with laptops on third floor I am having sporadic success at identifying the network (signal strength is poor but I sort of expected that) and at connecting but although I get an indication that the wireless network is connected I am not getting internet access.
Management do not want to pay for a second internet service and really want to use the connection they have coming into the first floor - I'm open to suggestions on alternatives or some hints on where I may have gone wrong with configuration.
Wireless access on the main floor continues to function without an issue.
