    Default Wireless Connection Speed Issues

    I have just added an access point to my network (CNet CWR-854 D), and I am having speed issues with it. The signal strength is great, the connection speed sets to 54MBits/sec, but I am unable to achieve more than about 4-5% throughput, even when holding the laptop right next to the router. The rest of the (wired) network goes great. Any ideas?

    Try the TCP Optimizer from this site, I have used it on my laptop wireless card & NICs on my 2 desktops and have seen a good increase in throughput.

    I used the optimal settings.

    Thanks for that, but it's not exactly what I'm after. I tried it anyway though - and it destroyed the usability of the connection, causing it to repeatedly drop to zero throughput. I restored the backup and it's now back to 5%. The cause of the problem is not with the Windows TCP/IP stack, as wired ethernet works fine. Any ideas what could be causing the issue? I am guessing an AP setting, as both the laptops I have tried have the same issue.

    Does the AP let you add MAC addresses of WLANS?

    Are you using them in ad-hoc or infrastructure mode?

    And if encryption is enabled (like if all support WPA, or better). Do they all have the same password?

    Yes, the AP does let me add MAC addresses of clients, but I currently have it set to allow all clients to connect. I am using it in infrastructure mode. Encryption is enabled (WPAPSK with 30 character key). All machines have the same key. The issue is not being able to connect - all the wireless machines work fine. The problem is the speed of the connection, which never seems to run faster than about 2.5MBits/sec. Even in the same room as the AP. Wired ethernet works fine, both when connected to the main switch & when connected to the AP's onboard switch.

    Hmm wonder if bridging the wireless and NIC will speed things up??

    Even tho the AP is 11.g is the laptop using 11g or 11b ?

    Have you checked for any firmware upgrades for the AP, also any driver upgrades for the wireless card ?

    AP is already in bridge mode. I have checked for FW updates, there are none (already running latest version).

    Could the problem simply be that the AP sucks? I tried disabling the encryption and the throughput doubled, but 5MBits/sec is still pretty shocking. I also tried using both laptops simultaneously - they both dropped back to 2.5MBits/sec. Strange thing is, the link is connected at 54MBits/sec. Return to place of purchase? Both laptops are using 11g.
