| Dynamic IP and my home network
Ok, here's my confused tale. Was running DSL with a static ip. Had the dsl line going into a BEFSR41, then going out to two different PCs. Life was good.
Then we switched to cable modem and a dynamic IP. I changed my router settings via the online utility to now get the ip automatically and life was still good. Now, suddenly, I cannot establish a connection through the router. If I connect directly to the cable modem, reboot the cable modem and disable/enable the lan connection, then I can connect just fine. From this I surmise the problem is somehow on my end.
In going back over my router settings I've only succeeded in getting myself thoroughly confused. I'm wondering if something is either logically wrong with my router settings or if something might be wrong with the router itself (or possibly the cabling in between.
ISP = Adelphia
OS = XP Home
Firmware = old, 1.39.1, never bothered updating it since everything was working ok. now i'm scared to update to the new firmware given all the horror stories about it.
cable modem = terayon tj 715
Any suggestions will be greatly appreciated. |

| Often cable companies tie the MAC address of the PC to the modem. Meaning any other MAC address would be rejected. You may want to clone the MAC address of your PC and see if that works: »Linksys FAQ »How and Why Do I Clone a MAC?

| set static ip on your computers that way you will have no problem going to the router when you are getting connection problems.. ( note : dns on the computer should be static to
you will find the settings on the status page of the router ) and also mac clone..MTU->1492... |

thanks lanik. i'll try that.
kennz sniper.....i'm not sure i understand what you mean. even when I'm having connectivity issues i don't have a problem going from the pc to the router. each pc can still 'see' the other, still print to the network printer, etc... it seems to be a problem from the router to the cable modem and beyond. can you clarify your suggestion for me please? |

| This is what kennz_sniper  is talking about: »Linksys FAQ »How do I set a fixed/static IP address on a LAN PC?
My motto has always been if it ain't broke don't fix it. See if cloning the MAC address works. You could play with the rest later if you want, once the problem is fixed.

lanik.....cloning the mac address didn't work.
now, one thing i found confusing (pardon the stupid question) is it appears that setting allows me to specify the WAN mac address. but i'm inputting the mac address of one of my pc's ethernet cards. by doing this am I telling the ISP that each computer on this network has the same mac address? if so, i wouldn't think that would solve the problem because i don't think it was related to this issue.
both PCs were accessing the network just fine. then we lost power and everything shut down, and when we fired everything back up i could not connect EITHER machine through the router. if i rewire to run a machine directly, each machine can connect just fine. so this tells me the computers themselves are fine, as is the connection from the cable modem to the isp servers.
when i rewire to run both computers to the router, the router lights indicate that the router is 'seeing' both PCs (all 3 lights are solid for each pc). I'm wondering if my setings have become hosed, but in going back over everything i can't find a problem.
i have host name and domain blank. i'm telling it to obtain an ip address automatically, and i've gone ahead and populated the dns servers in those blocks anyway. under login i have the options of PPPoE, RAS and disable and i've selected disable. connect on demand is selected.
for my computers' ip settings, it's set to obtain an ip address automatically and and same with dns.
i figure either something really complex is screwed up, or it's mind-numbingly simple and i'm just not seeing it. either way it's frustrating as hell. |

| If you are saying that when you connect the 2 PC's together with a crossover cable or through a switch or hub the 2 PC's connect (network) no problem, then if you connect them to the router and can't connect the network. The router could be hosed. and this is why you can't connect to the internet through the router. The router might of started to die back when you started having problems getting to the net and the power outage just finished the job.

I live in VA and Adelphia went down for several hours on 5-23-03 and was restored around 5:30 pm of the same day. I have not been able to connect through my BEFSR41 router ever since. (Everything has been fine for over a year till now.) I can connect through the cable modem if I remove the router. I tried another identical router with the same results. I have a friend on the other side of the county who has the exact same problem with the same model router. Cloning the MAC address doesn't work. The routers all appear to be functioning normally with the exception of no connectivity to the internet. Adelphia claims they haven't done anything to cause this and although they permit the use of routers, they will not provide tech support for them. I got lucky and talked to a nice technician who went through my routers configuration with me and ran some tests. My Linksys passed all of his tests and his conclusion was that the router SHOULD be working. That is all he could do for me. Adelphia has obviously done something they're not telling us....IMO. |

shootist...no, i'm saying that if I individually hook up one pc at a time to the cable modem in standalone mode, each pc connects fine.
interestingly, i hooked both PCs up to the router again to see if they could see each other. One could see the other, but not vice versa. I'm gonna go to best buy and buy another router and see if it makes a difference. If it does, i keep it, if not i return it.
sped....that's my fear as well. i'm not sure how i go from having no problems to now it simply won't work, period. if buying a new router doesn't solve my problem, then i'm going to have to wonder if the problem is really with adelphia, at which point i'm going to have to consider going back to dsl with a static ip. |

Can you ping the router? Do an ipconfig /all from the command prompt and see what it shows. |

Conejo, if you buy a new router could you get a different brand than Linksys? At least that would determine whether or not it is a brand-specific issue.
I have started a new thread in the Adelphia Powerlink section of the forums in the hopes of finding answers there.

Yes, I have been through all of that and much more. Thank you though.

my way.....ipconfig/all shows the assigned ip for that machine as the ip address, and 192.168.1.1 as the default gateway and dhcp address.
sped....that was my plan. |

Your ISP can't really tell how many computers are connected to your modem with the router. They could but it would detail a lot of complicated research they won't do unless someone is breaking their TOS. If you like I can get into that with more detail. All your ISP sees is that there is a MAC address connected to the modem thats it. Now if your ISP has restrictions on which MAC address can access the modem then you would clone the MAC address. Make sense now? It didn't work unfortunately.

If the cable system uses DOCSIS it can be a p.i.a. to re-establish a connection at times.
Try this:
1. Unlplug the router. Turning it off is not the same thing. Wait 3 full minutes. While you are waiting, unplug the router too.
2. Turn on the modem. Let it stabilize.
3. Turn on the router. Let it stabilize.
See if you then have a working connection. |

bcastner....already tried that. added to that drill was totally powering off both PCs, then powering on the router, then powering on the cable modem, then powering on the PCs.
More work, same result. |

| I have probs with the same router after adelphia has to run tests with me to clear up high latency issues. After I disconnect from the router and go straight to adelphia and try to reconnect the router I have to do a manual reset of the router ( push the recessed button in on the face ) and then go back into the router and set the MAC address gain. Then I have to power off the pc and once it boots back up everything is fine.
Try this:
Reset the router
(should be set to default ip addy 192.168.1.1)
p/w admin
set mac address
change password
reboot pc
connect to internet
change ip of router if needed then if you want specific
reboot pc
You should be fine now. |

You may also want to go to linksys and download and install the latest firmware update. |

jegedda....i have a question about updating the firmware. Mine is way old. I downloaded it but it appears you need to be able to simultaneously link up to the router via the online utility AND be able to access the internet in order to upgrade the firmware. That, obviously, is something I cannot do right now. I tried going to the help tab and upgrading the firmware by selecting the unzipped file from the download, but nothing happened and I eventually got a timeout error, I'm assuming because it attempted to connect to the linksys site and failed. |

I am a adelphia subscriber from Va.I have been using a linksys befsr41 router for over a year trouble free for the most part.Adelphia service went down for a few hours and when it came back on I couldn't connect unless I went directly thru the modem.I did the procedure you mentioned and more plus udated the firmware.I still can't get on and have 2 other friends w/ same brand routers w/ same problem.they have contacted adelphia tech support w/ no fix and have tried many fixes and info forums themselves.I sure wish I knew what happened? |

No, you don't need to be connected to the internet to upgrade the firmware on your router.
If you unzip the update file, it includes a document that explains how to do it. I use 1.44.2, Dec 13 2002. If you downloaded firmware 1.45 it is probably NOT a good idea to use it. That version has killed many a router and has been withdrawn. |
