3com 3CRWER101U-75: Not working.

Hi!

I went shopping to the mall that is around my house for a wireless router this morning. I didn't want to spend a lot of time on it so I basically bought the (almost) first router that I saw. It's a 3com router. A 3CRWER101U-75 (model WL-550, I think). I bought it thinking that it'd be a reliable router, even if it wasn't very powerful. As long as my wife could be connected to the net from our room, it'd be more than enough.

So, I arrived home about 4 hours ago. Since then I've been trying to get the damn thing to work properly and I just haven't been able to get it to work.

If I try pingin the router from a box that is connected to it by wire, the connection is intermittent:

64 bytes from 192.168.200.1: icmp_seq=3594 ttl=64 time=0.384 ms

64 bytes from 192.168.200.1: icmp_seq=3621 ttl=64 time=0.421 ms

See the wholes between 3599 and 3619? How about that?

Talking about the wireless, the only setting that is close to working is setting it to use WPA/WPA2 Only with TKIP+AES. And I say close because I only get to connect to the wireless on GNU/Linux with wpa_supplicant (running on the console) and even then it disconnects quite often. On windows, it's a no-go. And I'm talking about boxes that are less than 2 mts from the router while I do my testing.

Is it that I'm putting it under too much of a load while I do my testing? It's a very small router so I don't expect it to behave as a high-end router.... but even then... what's the firmware based on? Windows Vista?

I just can't believe it, really. I thought 3com products where reliable. At least this router doesn't make the company look good. What should I do? Is there a firmware update or something? Somebody help me, please!

PS I should have heard recommendations from a friend of mine who told me to get a WRT54G router instead, but I didn't get to see any at the mall, so....

Update 1
The wired connection has been working much more reliably today. So far, I haven't had any disconnections so far. However, the wireless is another story. Though the wireless can be seen by hosts, I can't connect to it:

CTRL-EVENT-SCAN-RESULTS

What should I try?

  1. I just upgraded the firmware to version 1.9 (the last, apparently).

    Same problems: intermittent connections, now I don't get to see the Wireless on the other boxes (the wireless is set to be broadcast).

    How about that?

  4. Well, after several trial & errors attempts I´ve managed to establish a stable wireless connection using AES(WPA2 only). So far so good, but I have to admit that I was also expecting a lot more from 3COM.
