Hey Jeff, you sound like you know a lot more than I do.
Here is the whole story.
I run 4 offices. All 4 offices are linked by a wirelss LAN. At my main
office I have my Terminal Server as well as my database server - both
2003.
Simply put, office 1 has a wireless access point (Senao long range
wireless multi client bridge) ( 192.168.10.149) - this then beams upto
my second office that has a bridge (Same hardware as above)
(192.168.10.150) this bridge is then through a crossover cable
connected to my newxt Access point (Senao again) (192.168.10.148) this
then beams to my third office which has the exact same setup as office
2, except the bridge and access points are now wired through a hub,
this allows me to connect my computers to the network.- Now the bridge
is 192.168.10.147 and Access point 192.168.10.146, the access point
beams to the 4th office with an ip of 192.168.10.145 Now any computer
at office 3 and office 4 can ping any other computer on the network -
LAN BASED.
NOW the problem - at office 2 - (my home) These access points are
miles up in the air. So instead of running ethernet cable to them i
bought another senao multi client effort. This i configured to a
bridge at 192.168.10.151 this little brifge connects to my
192.168.10.148 access point via wireless and I then connect that to my
little hub - all computers wired to this hub can see and run in the
network perfectly. Now when I try and connectto the access point with
my laptop - An Acer, it connects perfectly - 100& signal strength, I
assign my laptop a static IP as I do with all my computers - no
conflicts, I then try and use the network - NO GO. So i try and ping
differnet addressess like the access point itself - eg ping -t
192.168.10.148 I get no reply about 10 times then I get a reply (about
6 in a row) then 30 no reply's etc etc etc...
What I cannot understand is how when I plug my laptop inot my hub with
a cable - perfect, but when I connect to the unit wirelessly -
Intermettent. I have tried connecting mates laptops to the access
point wirelessly to, but they have the same problem. The WEP key is
correct, if it weren't I would be unable to connect.I have definitely
taken MAC address filtering off. I have tried resetting the access
point, nothing,
This whole unit used to work before the last access point got fried
but lightning or some serious electrical surge. I could work from
anywhere in the house wirelessly with my laptop. I did replace the old
unit with the same thing, setup the same way.
Obvioulsy i have different SSID's between each access point and
bridge.
I hope this helps you to help me as I hate being confined to this
desk.
Cheers
