Можно попытаться поднять PPP соединение на роутере через сотовый телефон  Siemens S55, AX75 .

Схема трёхпроводного кабеля  S55 data cabel

1) проинсталировать пакет PPPD

ipkg update
ipkg install http://midge.vlad.org.ua/kamikaze/ipkg/libpcap_0.8.3-2_mipsel.ipk
ipkg install ppp
insmod slhc.o
insmod ppp_generic.o
insmod ppp_async.o

2) создать файл pap-secret ( без него соединение будет разрываться )

midge# cat /etc/ppp/pap-secrets
"beeline" * "beeline"
midge#

3)запустить установку соединения

echo -e "\rATZ\r" > /dev/ttyS1
sleep 1
echo -e "\rAT&D0\Q0\r" > /dev/ttyS1
sleep 1
echo -e 'AT+CGDCONT=1,"IP","internet.beeline.ru"\r' > /dev/ttyS1
sleep 1
echo -e "atd *99***1#\r" > /dev/ttyS1
sleep 4
pppd 115200 /dev/ttyS1 -detach xonxoff usepeerdns local debug user beeline

using channel 35
Using interface ppp0
Connect: ppp0 <--> /dev/ttyS1
