I have a macbook intel version 10.4.11. I use a dlink 655 router with wep encryption. The router is on a different floor than I am and I live with several housemates all on the same network.

Generally, the connection has been working fine for me, although a little slow, but recently I have been able to connect for about 20-40 minutes and then the connection gets slow and then shuts down. When I try to rejoin the network, it says that there was an error. If I put the computer to sleep and wait about 20 minutes, I can join again, but the pattern repeats itself. If anyone has any suggestions how to fix this, I would be very appreciative.
