I've noticed that all of a sudden, the signal will drop dramatically, even disconnect, then reconnect at a different frequency from the same base station. The problem is that on the new frequency, I can't connect. The modem doesn't jump back to the normal frequency unless I physical reset it it (Push the power button). It then immediately locks back onto the usual frequency. I'm assuming that the two frequencies are just the different arrangements on the tower, as I normally connect at 2530MHz which is the 240 degree sector, and the other one is at 2518MHz, which is the 120 degree sector. If the 2530MHz sector drops, and then comes up, why does the modem not automatically lock back onto the stronger sector?
 
I seem to recall a similar thing happening to me when I borrowed a freind's modem.

The only way it was corrected was by closing all the IPWireless/Sentech software, resetting the modem, restarting the software and then connecting.

However, maybe you can use a cantenna to prevent signal loss in the first place?
 
How often does this happen aftermath, and what signal strength you getting from the 240 deg Tower and which Tower is it.
Also the modem will stay on a certain carrier until it dissapears before selecting another. This is something that needs to be addressed by IPWireless.

I seem to be having a similar problem. My signal strength varies between 12% to 2%. 3 lights to 0 lights I am using a Patch antenna.
From tower 50. As I am connected you see the lights going up and down like a yo-yo. But this doesn't happen all the time. It seems to do this only during the day. I am located in Park Town North on Jan Smuts Avenue. Must be the heat rising from the ground. Well at least it doesn't disconnect now, using the patch, before it disconnected.
 
I have spent the last hour fiddling with the alignment of this patch antenna and I think I have solved the problem....I think my station is at northcliff so I have been positioning the patch antenna at right angles to the direction of the station, and that is why the signal fluctuated so dramatically.

I now postioned the antenna so it was in line with the direction of the station 0 deg and voila I get a constant 13% signal strngth. Hope it stays there[:D]
 
Spoke too soon. The lights dropped back down to "no lights" and disconnected.
 
ProAsm, it can happen at any time. Sometimes the connection can hold for 24 hours on 2530MHz, which is the 240 degree sector. I only get signal from Mintek (Base Station 12), as I'm in Rand Park Ridge, and my antenna points directly at it, as I can see the Mintek building through the valley - about 4KM away (as the crow flies). Signal strength is 37-38% on the 240 degree sector, which is great, as there is 15m of LMR195 between the modem and the antenna.
 
Very wierd that I read this now, as my modem just did that for the first time about 5 minutes ago. I've got it hooked up to my firewall, which beeps when disconnected/connected. I noticed that the lights on the modem had all gone off except for the top right red one. They came back on a few seconds later.

Hopefully it doesn't happen too often to me.
 
I have a tower down here doing the same thing on one of its sectors.
Ok Mintek 240 and bb_matt do you know which Tower/sector you are having the problem with so I can report this.

It's only happened once so far ProAsm.

I connect via 82 in Randburg - I presume it's the Randburg Metro one ?

Aside from that brief disconnection, I've had no connection problems since I got up and running 8 days ago.
 
does anyone else have a problem wit the 128k package wen u click on modem options the max speed u can connect at is 115200 and not 128000. is there anyway to connect at the proper speed?
 
re the Max connect speed - this is something which I think happens with all users, not just the 128k package - apparently according to techie I spoke to a while back, each package is missing out on a chunk of u/l d/l speeds due to windows' 'max' connection rate.. There must be a tweak out there to bypass it, but I havent found it yet..
Of course if the techie was lying and I therefore am talking rubbish, I deny ever having written this :P
 
ProAsm, OK, it's just done it again - lost the signal on the 240 degree sector at 10:37am 12/4/2004, locked onto the 120 degree sector at 10:37am 12/4/2004. I'm sure no one is working on the Mintek tower at the moment, so it must be a hardware fault on the tower itself. It's a pain in the arse when it happens, because you can't reconnect automatically, and the modem requires a reset to lock back onto the 240 degree sector. If your PC is unattended, your connection is down until you manually reset the modem. Not good for Dynamic DNS etc.....
 
Brilliant - thanks for that report.
I now have something to check in the NodeB log.
Approx how long would you say the Node is down before it comes up again ?
Unfortunately I cannot do anything till Thursday [:(]

Yes, as I said before the Modem will stay on a carrier till it dissapears and wont connect to a stronger carrier, pity but thats how it is.

Just to keep you informed...ProAsm...It's still doing it, but now I can connect to the 120 Degree Sector, plus the 120 sector never seems to go down. Maybe I'm lucky that I can get a signal bounced from 120 degree's, but I assume there's alot of people that need to reset their modems.
