| I have a linksys router and comcast internet and i cant have more than one device on the internet at once. I can release and renew the ip address and that fixes it for a day or so, and then im back to where i started. Any suggestions? I tried turning mac address cloning on like google said, and that makes nothing work at all, and im too stupid to figure out where the problem is. So i decided to make this thread. |

unplug and turn off.
if you can find a reset button on the router hold it down and power cycle your router while holding down the rest button for about 30 seconds or so otherwise use one computer try resetting your router to the factory defaults from the web interface once the router is reset to the defaults - change the admin password and then begin bringing things back online one at a time If that does not work you will need to contact Comcast and or your local computer geek shop |

And yes ive tried resetting it. |

Get a local geeky teenager or the computer shop to assist.  my neighbor who does some kind of computery job told me to get a new router because linksys sucks. I figure if it works fine with one thing its gota be able to work with more than 1 thing. |

On the computer that can get Internet access, go to Start / Run / type:
CMD <enter> You will be at a command prompt. Type: ipconfig /all <enter> You should see one entry that has an IP address, and near it will be a MAC address, like so: Physical Address. . . . . . . . . : 00-26-C7-45-7F-90 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::4000:7410:1f45:4a11%12(Preferred) IPv4 Address. . . . . . . . . . . : 192.168.11.3(Preferred) The MAC address is the 12 digit hex number seperated by dashes. Write this down. Hold down the reset button on your router for a good minute or so to do a factory reset. Plug a network cable from the WAN port on the Linksys to your cable modem. Plug a network cable from one of the LAN ports on the linksys to your computer. Open a web browser on your computer and go to http://192.168.1.1 Username: admin or blank Password: admin or password Find the MAC address clone function, and enter the 12 digit hex number. |

Quick background on what your problem likely is:
Every ethernet device has a MAC address. Your service provider gives out an IP address which lets you on the Internet. If they have given an IP address to the MAC address of your network card in your computer, they won't give one to the MAC address on the WAN port of your router, unless the WAN port reports as being the MAC address from your network card. I suspect to get things working, you connected a network cable between your computer and a LAN port on the router, and the cable modem and a LAN port on the router. This way, your computer got an IP address from the service provider directly, which allows you to have internet access for a while, and no other devices have Internet access. You need to have the WAN port connected to the modem so that the router can act as a gateway to the Internet for all of the devices on your network. |

I agree with your neighbors opinion of Linksys routers. They either work and are solid or a nightmare. You could try seeing if an aftermarket firmware like Tomato or DD-WRT is available for you model. I kinda agree with that. I've had an older Linksys that you could bury in battery acid under 3 feet of cow shit and still connect to an Iphone from 3 miles. My mom needed a new one so I gave it to her because she was on XP and I couldn't get a damn thing to connect that I bought. I picked myself up a new Linksys that was supposed to be far and away better than my 4 year old one. Spent an entire day making that piece of shit connect to my Vista machine, 2 more hours making it connect to my wifes Mac, never could get it to connect to my droid phone which will connect to anything, and then 5 months later bought my wife a new computer (tonight) and just spent an hour making it connect to that after numerous resets, data transfers for setting from my computer to the new one, and finally just getting livid and turning off the WEP and running it unsecured before I set the SOB on fire. Some of them are great, some of them are so fucking finicky they should be burned for witchcraft!!! |

I know what your're talking about, and the information is solid. However, I believe that the concept behind the instructions is beyond your the skill of your intended. The OP said >"last time i set the router to default it took me a week of screwing with stuff i have no idea what it means to make it work again."< The OP is encouraged to find a computer savvy friend or a referral to an inexpensive technician who will do the work correctly and quickly. There is no shame in this, we all have our strengths and shortcomings. |

DO NOT USE MAC CLONING. Follow these steps: 1. Unplug the power from the cable modem and the router. If your cable modem is an Arris it should have a battery backup in the base, you'll need to pop that out as well. 2. Power up the cable modem. 3. Power up the router. You should now be able to get multiple devices online. If after a few days you cannot the problem is with the router, NOT with the cable modem. Some Linksys routers are good, others are crap. In my experience the Linksys routers with internal antennas (look sort of like flying saucers) are crap. Either replace the router or see if you can flash it with a third-party firmware like dd-wrt, OpenWRT, or Tomato. If you have to replace the router make sure your power cycle the modem to flush the MAC address of your old router from the modem. |

This is not always the case. sounds like your router may only be handing out 1 ip address but as others have stated without hands on it'll be almost impossible to tell exactly what the problem is and if you don't have the technical knowledge to troubleshoot the issue your best bet will be to replace the router. Comcast will actually GIVE you a wireless router for FREE you only have to pay shipping and they support the router and replace it if anything ever happens to it. Go to comcast.com/wirelessrouter to order it. |

If i download tomato or ddwrt or whatever, will it work after installing, or will i have to re setup everything. One other thing i had to do to get the router to work originially was change its address from 192.168.1.1 to 192.168.2.1 dont know if that makes a difference eta: i also have a old fios router here if theres any way i can make that work. |

You may need to reconfigure the router if you install a new firmware. The FIOS router should work, as long as the WAN port is an Ethernet port. Before you try it, login to it and make sure that the WAN/Internet port is set to acquire it's IP address via DHCP. |

BTW, I put together a wireless bridge solution yesterday for a friend that is damn pretty cool using 2 Linksys e2000 routers with dd-wrt. I got a good deal on them at $38 each. They are refurbs from Cisco with a 90 warranty. You can get them still for that price at this link http://digitaletc.com/computers/networking/wireless-routers/e2000-advanced-dual-band-wireless-n-router-refurbished.html Once you add it to your cart use E2000-22OFF as your coupon code. $38/free shipping (I bought 4 of them) Good to hear you got it worked out OP. |

I love DD-WRT but IMO it's better to use routers that support DD-WRT from the factory. Most of these routers will never brick and will always respond to a 30-30-30 recovery. |
