View Full Version : Wireless interference? Or problem with SB?

Mark,

Yes, you're exactly right. Before I saw your reply, I confirmed with USR Presales that the devices are indeed identical. My URS018054 cost around 60 (from PC World). I can buy the same device at eBuyer for approx 60. Whereas the 808054 is currently on sale (on same website) at approx 200 - even though they are essentially the same device (!)

Anyway. Are there any security settings that you've disabled or enabled that are no longer default (e.g. UPnP, gaming mode etc etc)? When I get back home, I'll get a summary of all my settings and mail it as a txt attachment. Would it be ok if you compared this to yours? Would be interesting to know if there is a setting somewhere that is causing all these probs... Although - again - things certainly seem a whole lot better after switching to static IP...

Thanks again!
Dan.

OK, so it's not that.

It's not impossible. I live in a fairly well spread out area, on the edge of school playing fields. So I probably only have 2 or three houses near enough to cause any sort of interference, and I think only one of them is probably enough of a computer user to possibly have a wireless network

I'll have to try NetStumbler on my laptop at some point to see what I can find.

I've never used them, but I get the impression that they are useless.

Yes, this is strange...

Just as

I believe that they are essentially the same box, but the 80854 is for the european market, while the 018054 is officially for the US market. I think I have the 018054, (bought from Scan.co.uk) but I'll need to check when I get home.

OK, so I have the following:

SSID - 13 characters, all alpha, mix of upper and lower case
SSID Broadcast - Disabled
Channel - 11 (NOT dynamic)
Authentication - WEP Shared key
Wep Key - 128 bit

Everything else wireless related is as per the defaults:
Beacon Interval - 100
DTIM interval - 3
Dot11 Mode - Mixed
TXRates - auto
Turbo Mode - Enabled
Frame Bursting - Enabled

I have a MAC filter setup with just known MAC's allowed (this
does not include the router itself).

Just about everything else, except my PP0E connection
is just the defaults.....

Hope this helps, but I suspect it won't.

Let me know if there's anything else I can do on this.

Mark,

I seem to remember someone on the list haveing a problem with "Turbo"
or "Burst" mode a while ago and once they had been disabled it they no
longer had the problem. Something about it not working properly in a
mixed b/g network.

OK, but it's working fine for me - I'm the one that doesn't
have the problem and trying to help find the difference with
those who do have the problem.

Thanks anyway.

OK, now I've had a new DHCP lease, after three days of
continuous playing. I have no idea if it was due to a
reboot or not since I was at work so wasn't around to
see it.

Is there a log setting for SlimServer which will log
such reconnects?
