How secure is this wireless connection?

I used to have WPA encryption setup on my wireless but as I'm running my server upstairs linking to the wireless router downstairs and communication between my games pc and server had to go over 2 wireless connections to get there it was problematic at best.
So I made the wireless connection via a wireless bridge using 2 Buffalo Airstations 54G but in bridging mode they only support 128 bit WEP encryption but there is a setting that stops clients logging on wirelessly to the AP's and I'm not broadcasting the SSID. This means that my games pc and the server share the same switch so can communicate faster.
My server has DHCP setup so that only network cards with MAC addresses in the reservation section are given an IP address.
The internal subnet address is 10.100.100.x / 255.255.255.240 so only allows 14 hosts and the IP is very hard to guess because it's not a well used subnet mask.

Can someone still hack the wireless connection and change the settings on the AP's to enable wireless clients logging on?

How secure would you say this is?

My problem with someone hacking my wireless is that they could use my IP to release virus’s onto the net and there’s a good chance that it could be traced back and also that person could: -

a) use my connection to download child pornography
b) save this type of images onto my machine and call the cops

even though the chance of this is very low but I hate people that look at/harm children with a passion so want to minimize the risk.

Well i can understand your reasons for having a secure network but given the effective range of a wireless network in reallity it would have to be a neighbour who would be hacking your network if anyone at all..............i guess you dont trust your neighbours then

I'd happly shoot them
But you could get someone roaming around in a car
