Mobile broadband connection 9.10 Huawei E1762
Slawek Drabot
A couple of issues:
1. On a clean boot with the modem plugged in, 9.10 does not recognise the modem. It recognises the storage part of the modem, but not the modem itself. Solution is to remove the modem and plug it in again, but it's annoying.
2. When re-connecting to the internet, sometimes I get a connection without being able to lookup http pages, i.e. no DNS or similar. Solution is to disconnect and reconnect, sometimes repeatedly, till I'm able to resolve domain names. VERY ANNOYING!
Any help appreciated.

The USB serial driver in karmic is broken. There was supposed to be a
post release fix for it, but it is yet to be released :(

Can you suggest tools to manually check/enable DNS to circumvent annoyance 2?

I have seen this happen with both optus and vodafone. Last time I used
3 they didn't seem to have this problem, neither does telstra. Maybe it
is just a problem with the huawei modems - dunno
If using network manager to control your connection there is an option
under the IPv4 tab to specify the DNS servers you want to use. I use
opendns for my 3g modem - 208.67.222.222 and 208.67.220.220.

Hi Dave,
I use wvdial on my Debian firewall/gateway/router and what I have done
to stop the changing of DNS stuff changing is:
<quote>
# cat /etc/ppp/peers/wvdial
noauth
name wvdial
#usepeerdns
</quote>
Note I have commented out the 'usepeerdns', this is so my
/etc/resolv.conf does not get over written all the time :-)
But under NM you can tell it to use set DNS servers that are provided
to you by your ISP. It under the IPv4 Settings tab. Change it from
'Automatic (PPP)' to 'Automatic (PPP) address only' which will open up
the 'DNS Server:' lower in that window.
Hope this all helps abit
Regards
Dale

No worries, enjoy. I use openDNS a lot when I travel, both with Optus
3g and further afield - the wifi in my currently hotel is rubbish so I
am using a static IP and openDNS without a problem. OpenDNS bypasses
the dns blockholing in china. Sure I give up some privacy for
reliability, sometimes it is the price I am willing to pay to be able
run my business on the road :)
