Wolfie Posted April 30, 2009 Share Posted April 30, 2009 I need to get into my ISP Supplied modem and take a look at the settings - i have been advised that the best way to get these settings is to use TELNET However, i'm not used to telnet, i vaguely remember using it sometime back in the late 80's - so i could do with some guidance/advice on what i need to do/how to do it... I'm guessing i just fire up a CMD promt and type 'Telnet' to fire up the 'program' or do i need to do somethign else? Anyone here a guru on the use of Telnet?

Prasert Posted April 30, 2009 Share Posted April 30, 2009 telnet is only a terminal emulator. You connect to a host with the command 'telnet <ip address' and it connects. Once you have a connection, the only thing telnet does is showing the data from the host on your screen and send your keyboard strokes to the host. That's it. What to do next totally depends on the system you're connecting to. In case of your router it will probably be some stripped down version on unix. Try typing 'help' to get started.

Crossy Posted April 30, 2009 Share Posted April 30, 2009 Telnet doesn't come with windows any longer Not in Vista, W2k has it but not sure about XP. To be honest it's likely far easier to use the web interface that most routers have, try http://192.168.1.1/ in IE or Firefox. Link to comment Share on other sites More sharing options...

XP still has telnet! Just open the command prompt (Run + CMD) and type telnet followed by the IP address of the router. But you'd need detailed info on the router on how to go about changing settings! Link to comment Share on other sites More sharing options...
webfact Posted April 30, 2009 Share Posted April 30, 2009 For W2K and XP Telnet command http://www.computerhope.com/telnethl.htm Link to comment Share on other sites More sharing options...
stumonster Posted April 30, 2009 Share Posted April 30, 2009 or use a copy of putty portable. I would expect the modem to have a web GUI - if not you will be a while poking around the directory structures looking for the config file you are after Link to comment Share on other sites More sharing options...
guava Posted April 30, 2009 Share Posted April 30, 2009 If it is a relatively new modem/router it should have a web interface accessible via any web browser. Running ipconfig/all from a command prompt should give you the IP address - the modem/router is the default gateway on most small/home networks. If it's a USB modem, the only way to change the config may be via software provided with the modem. If you don't have the software you shoyld be able to find it online. Google the make and model for more info. Or post details here and someone may take pity on you, but its far quicker and easier to google it yourself. ISP supplied modems are usually pre-configured, so not sure why you need to change anything, or whether the advice you've been given is valid.

Wolfie Posted April 30, 2009 Author Share Posted April 30, 2009 What i am trying to do is to get hold of the settings on my ISP modem and compare them to a new modem i have... (see the other thread about Linksys WAG160N) - as i have established that the Linksys modem settings are at fault. My idea is to compare all the settings from my ISP supplied modem, one by one, and try to figure out the difference - then either set the missing/incorrect setting in the Linksys myself or - if it is not settable - log a ticket with Linksys to help me fix the problem... Both modems have a web interface, but the ISP modem has a cut down web interface and i was hoping that going in via Telnet i could 'view' the missing settings - you know how these ISP's like to prevent you from seeing/changing some settings. I wanna know what all these 'advanced' settings are pre-set to Link to comment Share on other sites More sharing options...

I wanna know what all these 'advanced' settings are pre-set to The only settings required for adsl: VPI/VCI circuit numbers PPPoA or PPPoE setting PPP username (usually <phonenumber@realm>) PPP password If the connection doesn't come up, try a mtu setting of 1452. As for telnet versus the web-interface: The web-interface enables everyone to configure a router with just the information mentioned above. In telnet, you will probably have to configure everything yourself, and you'll see settings that you didn't even know they're required! The ISP should provide the IP address, default gateway and dns addresses. Link to comment Share on other sites More sharing options...
Wolfie Posted April 30, 2009 Author Share Posted April 30, 2009 (edited) i get/have a connection - but it drops/reconnects every 10-15 mins - which the ISP modem does not. I have tried all available firmwares (1.00.09, 1.00.10, 1.00.12) - before anyone suggests updating firmware I've tried several MTU's ranging from 1300 upto 1500 (raising in increments of 25) The VPI/VCI settings are correct as per the ISP's specifications, the 'Keep alive' setting is a default 30secs - The Wireless connection (local) is strong and i have no problems there (obviously internet access drops when the modems ADSL connection drops) Any ideas guys? /Edit: Here is the log file entries - in case anyone can gleen any information from them Thu, 2009-04-30 23:29:35 - lcp echos pending >= lcp_echo_fails!

Prasert Posted April 30, 2009 Share Posted April 30, 2009 Nasty one. According to the log, the connection over the phone line drops. That's the (DSL-)link between your router and the DSLAM. Normally I would first look at the signal quality of the line (SNR and error counters), but you already mentioned that a different router works flawless on the same line. There's not much to configure in a router for the basic dsl link. It's a physical link, which is completely handled by the chipset in the router (usually Alcatel or Broadcom chips). In your router it's probably a dodgy chip - which can have any cause like power surges / lightning / anything else that can damage electronics. Anyway, on this level there's nothing to configure. This chip only uses the VPI/VCI number to put a signal on the cable, the negotiation with the dslam is done by the chip itself. Link to comment Share on other sites More sharing options...
Wolfie Posted April 30, 2009 Author Share Posted April 30, 2009 A friend of mine has the same modem/router - his disconnects every 8hrs (he is on KSC net connection, i'm on ToT) - i gave him my modem to test and he reported that it functions fine at his place (usual disconnect after 480mins) - as i test i have borrowed his unit and tried it at my place - same result - drops every 10-15mins Ive ran a D-Link 2640T and the ISP router on this line - both operate fine, its just this *pig* of a router thats giving me hassle Link to comment Share on other sites More sharing options...

Yeah looks like im screwed until Linksys fix this problem with a firmware update My ISP gave me a Thompson ST536 v6 'Speedtouch' modem - looks like im gunna be using that for a while someone wants to get a better ping? Actually i was looking for a solid wireless, cos my old D-Link keeps dropping wireless all the time, it is 2 years old, time to retire it Link to comment Share on other sites More sharing options...
