Wireless Question

Postby leekirb » Wed Sep 15, 2004 3:59 am

What would cause a "running perfectly well wireless system_one wired two wireless_ for six months" to all of a sudden not work for 6 hours. The wired worked of course but neither wireless system? Hacking? I am using MAC addresses. Something else?
Thanks.

Just 6 hours and then go back to normal?

If you are still running with the original username/password combination that came with the router, I would suggest updating it ASAP.

Do you use WEP?

Switch to SSH if practical.
Both MAC filtering and WEP can be sniffed out with sufficient number of packets.

That would take weeks, maybe even months before the right packets are found.

Did you try moving the wireless devices closer or to different areas?
Was the signal completely dead? Are you using the Windows manager or program client included with the wireless device?

What's ssh?
Anyway I am using windows to manage my connections, and the little icon said "little or no connectivity".

That sounds like RF issue then. Did someone do some works and use PRS (CB)? A new radio/cellphone tower put up recently in the neighbourhood? Cordless phone? I can't think of what else would cause that, but smells like RF issue.
BTW SSH is Secure Shell, encryption technique considerably more resilient to hacking, but tends to slow down large networks. Also requires support by the router.

Just to throw something in - I can't really tell what happened to cause your problem, especially since it magically fixed itself.
But I recommend using a config utility bundled with the wifi card instead of the Windows network config.
DLINK, LINKSYS, etc all come with them.
