HSPA idles, then doesn't connect.

When I finish loading a page, my connection switches from HSPA mode to 3G (idle), which i assume is my radio releasing the HSPA channel. When loading a new page, it will take maybe a few seconds to find another channel, which is fine.

Except, sometimes, it gets stuck on idle mode, and it usually connects after a while (sometimes 1 or 2 mins), but after resetting my apn or renewing my ip it connects to HSPA immediately and the page loads. Why does this happen, is it a lack of HSPA channels or something? I'm using a Google-HTC Nexus One, is it a problem with my radio? Reception has nothing to do with it, I'm in areas with full bars of reception.

Thanks.

Typically your device drops down from HSPA to WCDMA/UMTS (3G) when the service is idle, but it should be within seconds (unless signal is poor or drops down to GPRS) that it connects back up at HSPA.

There should be no significant delay in this occurring and sounds more to me like something to do with the phone or similar.

Such as my phone, Nokia N97, when idle, it drops to 3G, then as soon as data is requested, it jumps back upto HSPA and retrieves the new data.

Linux and E169 Modem [switching]?

My email to Residential Support:
"I am having problems with my Huawei E169 modem and Linux.

Please note:
1) I bought the modem from VIRGIN BROADBAND before moving to Exetel;
2) I then reformatted the modem & firmware using Huawei's own tool. This replaced the Virgin firmware and software with Huawei's firmware and "Mobile Partner" installation files.
3)I have always been able to connect via Windows.
4) I have always been able to connect using Linux after two attempts.
But now:
5) I can connect to Exetel using any of my 3 machines when booted to Windows XP
6) None of my machines now connect via Linux.

I have come to be of the opinion that Huawei's "Mobile Partner" connection software for Windows is able to force the modem to change its internal protocol settings to HSPA/GPRS/WCDMA/[etc] so as to connect to the network.
Linux's Gnome Connection Manager, however, does not have this capacity and this may explain why I cannot connect.
Have there been any network changes in the Alice Springs region?
Do you sell any improved modems ?

Steve Peters

I actually use my HSPA service using the Huawei E169 via linux and have no problems, it being, all the computers in my house and my laptop all have linux.

I don't use gnome, nor any component of gnome.

I happen to use wvdial to make the connection.

You can actually specify what network to connect to (GPRS/WCDMA/HSPA) via the use of AT commands, which you would need to obtain from Huawei.

I however don't require the use of any of these and the connection works perfectly fine.

Sounds like your linux connection has always been dodgy. Before looking for network problems, try to debug that - check the logs, try using wvdial etc.

One common problem: if it seems to connect ok but you can't browse it'll be because the connection didn't pick up the nameserver information automatically. In this case, try entering the exetel resolvers manually (NM -> Edit Connections).

Edit: and FWIW, I've used an e169 and various phones with both Gnome-NM and (in the past) wvdial - with the correct settings, all worked.

Exetel support phoned today.
They checked reception in my area and the results of my successful & failed connections. They recommended that I set my connection to WCDMA only - and on the 900 band.
So that's something prettty much like I'd come to expect to work
However, I won't be doing anything before I install the imminent release of Ubuntu Lucid.
