kudos:1 | Is my router dead/dying? I have a Linksys BEFSR41 router to give the ATT DSL to my two computers and also network them. When I connect the dsl modem to the router and then the router to my computer I don't have internet access. That was working. I can access the router at 192.168.1.1 but not the modem at 192.168.0.1 . However, if I connect the dsl modem directly to the computer, the computer has internet access. All the devices are turned off while I make the connections.
One oddity is when I have connected the computer to the modem and everything is turned on, if I remove the end of cable that goes to the modem and I plug it into the router, and use another cable to connect the router to the modem, then I have internet access for about 2 hours.
To recap:
when I connect the cables while the devices are off
A. DSL MODEM -> COMPUTER: Turn on and OK.
B. DSL MODEM -> ROUTER -> COMPUTER: Turn on and NO CONNECTION.
when I connect the cables while the devices are on
C. Go from A to B: connection works for ~2 hours and then dies.
D. Go from B to A: connection works.
Is the router dead/dying? If so I'll have to get a new router. I think linksys doesn't make the BEFSR41 anymore so I can buy a refurbished BEFSR41 from the Linksys store:
»homestore.cisco.com/viewproduct.···54377587
or some other router with the same functionality.
What do you think I should do? Any router recommendations if I need a new router? |

| Just a suggestion but try changing the starting IP of your linksys router to something a little different. I do the same in my setup with my cable connection. Also that router is super old, i think its only good for up to around 6 mbps or so on the WAN side. I used to have that router so I know its limits. |

The router starts at 192.168.1.100. Only the last number, the 100, is editable. To what should I change this? If I change it, are there any other values that I should change? Other values on the router are: obtain an ip automatically, local ip: 192.168.1.1, subnet mask 255.255.255.0, number of addresses: 50, dhcp range: 192.168.1.100 to 192.168.1.149.
I don't have a firewall. I have avira antivirus (up to date). A search for viruses came up empty. Same for rootkits.
UPDATE: I set the 'start ip' from 192.168.1.100 to 192.168.1.200 and it works! no router reboot. I was connected through the router even though there was no internet access because that was the only way I could access the router interface at 192.168.1.1. After the change, I clicked save and internet access was back! Now, the DHCP range is 192.168.1.200 to 192.168.1.249. I only have two computers. wasn't 192.168.1.100 to 192.168.1.149 enough for 2 computers?
Also that router is super old, i think its only good for up to around 6 mbps or so on the WAN side. I used to have that router so I know its limits. |

| Well I personally have always preferred linksys and netgear brands. Never had any problems with either and I have heard more good things than bad. But if I were you I would get one with wireless N on it, bestbuy has some good ones for about $80 bucks or so.
And for the IP changing thing I have had a similar problem with my cable connection when I was giving a trial run of this router combo modem. The thing about the IPs is that the combo modems (dsl or cable) have IPs similar to that of most routers default settings which is why I have always changed the IP on my router first thing whenever I hard reset it. |

kudos:1 | do I need wireless N if my network is wired? my laptop has a wireless card I haven't used. my desktop has a built-in wired card. if I get a wireless router can I connect my desktop with an ethernet wire and my laptop with its wireless card?
I'm a bit apprehensive/afraid to go wireless in my desktop fearing some hacker will break in. I don't really care about the data in my laptop! |

| Even if you don't need wireless right now it can be disabled. Think of it this way, it will help future proof your computer hardware for when you will need it and besides nearly all routers these days come with wireless built in them so its pretty much unavoidable but the wireless radios can be turned off easily. |

kudos:1 | I was looking at newegg's netgear routers. Here's a Wireless-N router:
»www.newegg.com/Product/Product.a···33122235
this must be the same, but with dd-wrt:
»www.newegg.com/Product/Product.a···33122334
I see 1 WAN port and 4 LAN ports on both. Are these OK? |

| That 2nd one is the same one I have but mine is from the Samknows broadband testing project. It has the stock firmware but its been slightly modified to run the tests and stuff. Not real sure if that one you linked would come with DD-WRT but I think it just means that you can put it on there if you want because I do recall its one of the supported routers. I might try to flash it on this one once they are done with the testing. |

kudos:1 | well, the problem came back!
seems some time (2-3 hours) after I connect a 2nd computer to the router, the router gives up. what I do is unplug the ethernet cables from the computers to the router, and then plug in the ethernet cable of the 1st computer only to the modem. and the connection to the 1st computer works. then I can remove the ethernet cable of the 1st computer from the modem and put it back to the router and the connection to the 1st computer works again.
and as long as i don't insert an ethernet cable from another computer in the router, the connection to the 1st computer keeps working.
can the router not be able to handle only one computer only? |

You most likely have double nat setup conflict.
Both the modem and the router are routing. |

My speedstream 4100 modem at »192.168.0.1/ says:
Mode PPP on the modem (Public IP for LAN device)
Can the modem do routing while it is in pppoe mode? I did google searches on 'double nat' and 'double nat conflict' and started reading and now I'm very confused! |

kudos:1 | ok, I got a netgear wnr1000 router. after I connected it things work fine again.
right now I have the 'enable wireless router radio' setting unchecked. if I checked it, set up wpa2, and then set up the 'wireless card access list' where you give the MAC number of the devices you want to be able to use the router, will my network be ok security-wise? |
