Question about Linksys (WRT54GC) Router

3 Answers

My internet is dead after adding router, help please

Hi, I've recently set up wireless using a linksys WRT54GC router, my cable modem is a Motorola SB5100E surfboard ,it took a long time to set up as the PC kept rejecting the connection, anyway I managed to get it woking and it seemed to be fine, last week my net connection suddenly went off, although all the lights on the router were showing as ok, my Modems lights were out apart from 'recieving' which was just flashing and I could not access the internet at all, eventually I got onto the router help screen (the one where you type your IP in) and I just refreshed something and hey presto the modem burst into life again, the problem is now that it has done it again last night, all of a sudden my connection went down without warning and nmo matter what I try it will not come back on, is this a common problem and what can I do about it? I'm not great with computers so please go easy on me. Im currently at work on the net and not with my pc.

Many thansk Pete

First, it could be that you have a dysfuntional Surfboard, and the first thing I would do is call my ISP to have then check it from their end... also, have then check the levels (db) and make sure that they are in the correct range for your area...

They may want to blame your Linksys for the problem, but believe me, this is just the ISP trying to push the blame off onto you.. Your Linksys is just a router that does NAT, and the modem has no way of 'knowing' that you are running a NAT'd device behind the modem.. After the data packets leave yoru router, they are all encapsulated (according to OSI Model) and appear to be from one device.

My bet is that your Modem is bad... JMHO though..

There is a soft limit with in router manangement software, which limits the number of threads/session connect from your pc via the router to the internet, if by any chance the number of threads go beyond that limit, the router will "crash".

Upgrade the firmware of your router might be a good choice, but make sure you use ethernet connection with a cable rather than do it wirelessly, as you might end up with a bricked router, which is recoverable but not quite easy.

Dear Pete37038,

I think your problem might be in the set-up of your router and modem, the following must be check to see if your modem is working ok.

1. Disconnect your router cable from your modem and connect your computer by a cable directly to your modem. if connection is restored, that means your ISP connection is good.

2. If 1, turns out ok, then set - up your router properly taking into considerations the seetings must match that of the modem. Cosidering you are not geat with computers; you would need an expert to do that.

3. Try the manual of your lynksys, there is an instruction that accompany how to set it -up properly to a modem.

4. Make sure the WAN port of the router is the one connectected to the ISP Modem.

5. Normally, Linksys comes with a quick install CD, Try it and follow the prompts and answer them. The informations that it will ask must be provided by your ISP provider.

6. If you have set - up your router correctly wired to your modem; then you have to set-up next your wireless connection.

7. The fastest is to access your router with youe explorer using its default TCPIP address and password. your manual for linksys will give you this info.

8. Use MACaddress filtering to avoid other nearby computers to access your WIFI spot.

you have to refer to your manual of Linksys and your ISP for the needed information to properly set-up your router.

I just received this in the mail and I am now trying to hook it up for wireless internet and phone service. HELP


First step: You need to make sure that your internet service is active that means the modem provided by your internet service provider is working.
next connect this router to your modem with ethernet cable provided. Use the WAN port of this router to connect to your modem
you are done with wireless part but you need to log in to the router to make it secure! If you need help with that please send a request!
Once you make router secure connect your phone service device (IP Phone) with ethernet cable to one of the LAN ports of the Linksys router. Power cycle (power down and up all devices) once if necessary!
good luck!

Hi

If you will be switching to a different internet provider what you need is to get their network settings.Most of the time if its DSL or Cable connection all you need is just your account name and password from them for the router to talk to your modem. Thanks

Has your modem been hard reset recently? if so, it may require that you bridge the modem out to work with the router- ESP. if you use Verizon DSL. If so, contact your ISP, and ask for assistance in bridging out the modem.

My WRT54GC won't let me into the control panel. I've looked up the solutions for hours, and i can't get it to work. I'm using a MBP and a HP Pavillion dv6000, and it's the same with both of them. If i...


If you connect the router (WRT54GC) to your broadband modem does it then allow wireless action? Your router has an Internet address. It is 192.168.1.1, in all probability. Check your manual to be sure. Access to the control panel is through this address. You must log in to the router then set up the Wireless, the SSID (the name you give your network) and any security you set up. I prefer the WEP-PSK[TKIP] as it's easiest. Other things with the router, settings and such, pretty much are set automatically, so once security is set you should be good to go. Good luck !!!

Hi, I'm an idiot! PLEASE HELP


you may be suffering from mixed Cat 5 and Cat 6 cabling.
The wiring is slightly different and they don't work well when mixed in routers and modems etc. One or the other will work , but when they're mixed it'll do what you have going on here...

I would recommend wiring everything with cat 6 ethernet cabling. Look on your cable and you will find the labeling on the outer casing.

Motorola SB5100 and linksys router connection


The only thing that you need to setup on your Linksys for it to work with cable is to make sure that DHCP is enabled on the router.  You will need to plug your router into the modem via the ethernet cable and then plug your neighbors pc into a link port on the router (the cable modem plugs into the internet port)  You will also need to follow the reboot procedure.  Power everything off. 
1: Turn on the surfboard and wait about 1 minute for the surfboard to make a connection with your ISP (the link light should come on).
2:Turn on your router and wait for your router to sync up with the surfboard . 3: Turn on your computer. Whenever you plug anything into a cable modem, you must recycle power to the modem.  It "remembers" the last device that was plugged into it, so it's memory needs to be cleared.

Setting Up a Wireless Network


You can still use your existing Linksys router with your cable modem. In fact the router your have is designed to work with DSL/Cable Broadband connections.

1. Make sure to properly connec the devices in your network. Modem will be connected to the Internet port of the router. Then, laptop will be connected to one of the 4 Ethernet ports of the router. For initial setup of your router with modem, you need to hardwire laptop to the router.
2. Press and hold reset at the back of the router for about 15 seconds.
3. After 15 seconds turn off the router and then turn off the modem. Wait for a minute.
4. Power on modem and wait for the lights to be ready.
5. When modem lights are on, turn on router.
6. There should be 4 lights on. Power should be steady green. Internet, WLAN and Ethernet port.
7. Checked if you have Internet connectivity on your laptop while it is wired to the router.
8. If Internet is working, disconnect laptop from wired connection to the router and check available wireless network that laptop can detect.
9. The default wireless network name that the Linksys router broadcasts is "linksys". Connect to it which is an unsecured wireless network.
10. Once you are successfully connected, check Internet.

Hope this helps!
