connecting a usb 3g modem

2008-08-31 Thread Thomas Bertani
The usb modem is recognised succesfully by the kernel,  just simply
configure ppp to get it connecting to the net.
I tried with the huawei 270 modem and I succesfully connected but I can't
ping anything... it is because the modem need one usb 2.0 port or two usb
1.0 ports?

I have the wire to connect the modem to two usb 1.0, so just but a usb hub
for the neo?

I have one of these, they are nice.

I would look at

route -n
ifconfig -a
cat /etc/resolv.conf

Sometimes when I use it on normal laptop, I get bogus DNS in UK.

Dunno, see how you go, might be OK direct.  Or maybe the ping problem is
that... mine has an LED that goes blue solid when the modem is
authenticated and has comms to network provider.

You mean like if you use
   host somedomain.com
on your Linux system, when using the modem as the DNS server, you get
complaints like "malformed response" etc.?
I have had this complaint with ADSL modems - both Huawei and DLink.
The solution is to set your Linux host's resolv.conf to directly query
your ISP's DNS servers, or OpenDNS servers, or to run a caching DNS on
your Linux host, possibly with ISP nameservers or OpenDNS servers set
as forwarders.
Surprisingly, that proprietary OS that most FOSS people hate to use...
works just fine with the DNS implementation on the ADSL modems... a
case of two brokens make one "fixed"? :-P

Cheers
Ed.

No the dhcp client puts the DNS nameserver lines in, but they don't
always work.  There's another issue on my box somehow that later,
NetworkManager overwrites it with old DNS nameserver line somehow, but
now I realized why my connectivity breaks I stop NetworkManager for the
duration and that solves it.

Dread to think of it.

No I have no error with ping, only I don't receive answers and I loss all
packets...
