So ive been trying to use pppd in n900 over bluetooth dun (with kp53) to connect to internet via nokia 2690 phone with instructions from Matans thread and googling a lot of sites. I finally made it work after getting the right chat script and it was working just fine... until for some reason while conected via pppd my phone froze and had to restart it. After that it never worked fully again, fully because i can ping/access any site via ip but in not able to visit domains, also im unable to ping my peer it results in 100% packet loss, i can ping nameservers successfully. I think its probably a dns or route problem, what do you guys think.

My chat script:
Code:
ABORT   'BUSY'
ABORT   'NO CARRIER'
ABORT   'ERROR'
TIMEOUT 5
REPORT   CONNECT
''      AT
OK      AT&C1
OK      ATZ
OK      AT+CGDCONT=1,"IP","Tata.Docomo.Internet"
OK      ATDT*99#
TIMEOUT 30
CONNECT    ''
Options file:
Code:
#dump
#460800
#115200
#nocrtscts
#defaultroute
#replacedefaultroute
usepeerdns
noauth
lock
#noip
noipdefault
ipcp-accept-local
ipcp-accept-remote
debug
nodetach
#persist
#passive
#default-asyncmap
#asyncmap 0
noaccomp
nobsdcomp
nodeflate
nopcomp
novj
noccp
novjccomp
refuse-chap
user "blank"
password "blank"
Also is this the default /etc/resolv.conf on n900? this is my current one:
Code:
nameserver 127.0.0.1
nameserver ::1
pppd log:
Code:
abort on (BUSY)
abort on (NO CARRIER)
abort on (ERROR)
timeout set to 5 seconds
report (CONNECT)
send (AT^M)
expect (OK)
AT^M^M
OK
 -- got it

send (AT+CGDCONT=1,"IP","Tata.Docomo.Internet"^M)
expect (OK)
^M
AT+CGDCONT=1,"IP","Tata.Docomo.Internet"^M^M
OK
 -- got it

send (ATDT*99#^M)
timeout set to 30 seconds
expect (CONNECT)
^M
ATDT*99#^M^M
CONNECT
 -- got it

send (^M)

ifconfig ppp0 output:

Heres what route -n shows after pppd connects:
Code:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.6.6.6        0.0.0.0         255.255.255.255 UH    0      0        0 ppp0
And heres what route -n gives with defaultroute and replacedefaultroute enabled in options file:

Code:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
