I have had many wireless problems in my apartment and have tried several options. I just bought an AEBS for the dual mode capabilities hoping that running 5ghz would help to solve my wireless woes. I was previously using a netgear wnr2000 and was getting pretty bad speeds with that. I have a 2mb/s connection but would often test only 500k/s. I have also tried the combination of the netgear and an airport express running at 5ghz only, but my computer couldnt even recognize the 5ghz network. So today I tried running the AEBS and found that when connected to the 2.4ghz network, I was getting upwards of 800-900k/s (which is better than before but still less than half of what my full connection is), but when I connected to the 5ghz network, the speed dropped as low as 10k/s and the connection even timed out a couple of times. I have tried several different channels with no improvment My router is now situated only about 25 feet from the router, but has to go through a couple of walls. I am using a macbook pro 2.4 Ghz intel core duo with 4 GB of RAM. I dont have anything else in the house running at 5ghz. Any suggestions? Thanks.
