There may be a number of reasons why you may find the Traceroute failing at certain points
( from the ISP blocking ICMP packets, to incorrect routing, to physical line disruptions). An
email to the ISP of the network which contains the problem or even an email to your Network
Administrator will get some answers.
If the Traceroute results indicate the subnet in which your Router is in (or its Gateway IP),
then it is possible that your Router is powered off/malfunctioned or there is a cable/switch/hub
problem.
NOTE:
MS Windows uses 'tracert'. Other OS' usually use 'traceroute'.
Telnet
Use the Telnet command to connect to the TCP port of your PocketPAD. You will observe data
received from the connected serial device. You can send data to the serial device as well.
If you are unable to connect to the configured port, check your Router settings. If you have
made changes, you need to reboot the Router for it to take effect.
Check the Network Application settings. If 'Remote Host/IP Address' (and/or 'Remote Port')
is configured, you will need to connect from that specific host (:port). If the 'Application Type'
is active, you won't be able to telnet to the port (set it to Passive to test). Try 'telnetting' to the
Remote Host's port to check if it opens a socket.
How many hosts are connecting to each Network Application?
A maximum of 5 TCP and/or UDP network applications can be configured on the Router. Each
application can handle 5 socket connections (Total of 25 concurrent socket connections at any
one time with all applications configured as Passive).
Web Browser Proxy Settings
Check your Browser Proxy settings should you be able to successfully Ping the Router, but are
unable to connect to the Router's Web Configuration.
If the Proxy is enabled, traffic is directed outside the LAN to the internet via a gateway. If you
cannot alter these Proxy settings, try using Telnet Configuration to alter the Router parameters.
