Question about Linksys Wireless-G WRT54GS Router (e125894)

1 Answer

Getting knocked off

We have several computers in our office that work off of one wireless router. We've had tech services from our Internet provider out this week to work ont he DSL lines, and that seems to be fine, but for some reason, a couple of our folks cannot log on.
They get an error message stating that "cannot connect to this profile".
Anyone know what that means?
Thanks

Sounds like you might have a wireless signal problem, or if your wired it could be the DNS problem I've heard about.

SOLUTION THAT WORKED

Install a bios that is from the DD-WRT group. Here is more information:

http://lifehacker.com/software/router/hack-attack-turn-your-60-router-into-a-600-router-178132.php

Wikipedia covers this here:

http://en.wikipedia.org/wiki/DD-WRT

I would be happy to help you and anyone else who wants to turn their 'low end' routers into vastly more reliable devices for free with this upgrade (which is free).
Boost your wireless signal The first thing I did after I finished the firmware upgrade was give my wireless signal a much needed boost ("needed" in the sense any signal boosting that can be done needs to be done, right?). Doing so is trivial.
Go to the Wireless tab, then to Advanced Settings. Find the entry labeled Xmit Power, which is set by default at a paltry 28mW, and can be set up to 251mW. To be honest, I don't know much about the science of the whole process, but I do know that 251 is WAY bigger than 28. However, you probably don't want to pump it up to 251mW right away.

The DD-WRT manual suggests that a "safe increase of up to 70 would be suitable for most users." Anything too much above that and you'd be flirting with overheating your router and damaging the life of your router (though I've heard that many people have pushed it up to 100 or above). So go ahead and change your Xmit Power to 70 and click the Save Settings button at the bottom of the page.
I can't measure for sure how the signal boost has improved things for me since I've just moved into this apartment, but I can say that the signal is full bars pretty much anywhere I go. How's that for scientific?

Dlink wireless internet stick does not complete installation, stops at languages


clarification in regard to the instructions that came with the installation package, I learned that you first have to connect the modem/wireless router to the PC with an Ethernet cable, before you can actually go wireless! Once I relocated the computer to where the router was, the tech service person got all the necessary info from me to activate the wireless feature, and I was then able to haul everything back to where I'd had it in the first place. I also had to get a USB wireless adaptor, with the tech service for its manufacturer helping me to get it set up. (Obviously, I'm pretty helpless on my own. frown.gif )

The setup has worked pretty well since then, except that every once in a while, like you, I have to "repair" the wireless connection. But on two occasions I was not able to connect to the Internet, getting the message: "Internet Service Provider Not Found." At those times, the Internet indicator light on the router was red instead of green. After I disconnected the power supply to the modem and then reconnected it, it reset itself, the Internet indicator turned green again, and I had no trouble getting back on the Internet.

If you haven't already done so, you might check the Internet indicator light, and if it's not green, try resetting it. And if none of the suggestions offered by other people on this site solve the problem, I'd contact your ISP's tech service and/or the wireless adaptor company's tech service, to make sure everything is properly configured. I have found most of the tech service people I've dealt with to be patient and helpful.

Hi im trying to get my wireless to work on my lap tops and i can not get to work on them can you help me plz thankyou


If there is several computers that cannot connect wireless to the internet, you have to check out you wireless router. First of all, you should try to unplug the power for about 10 seconds, then plug it back in and check if it is working. If not, you should try to connect a computer directly to the wireless router, if possible, with a network cable. If that is working, then it is something wrong with the wireless settings, perhaps interference. If that is not working, you should try to connect directly to the internet with a cable, use the cable that is connected to your wireless router. Plug it into the computer instead of to the wireless router. If that is working, there is probably something wrong with your wireless router, and you should get a new one or deliver it to repairing. If the direct connection dont work, you probably would need to call your ISP (internet service provider). I hope this would be of any help for you, and dont be afraid to ask if you need more information.

Will the WBR-2310 work with my wireless internet service. I don't have DSL or Cable or Satellite. I have a wireless service from a local provider.


Hi,

YES but you need a computer which will bypass your internet service from computer to router and then any wireless computer or any WAN enable device will access internet.

Share your wireless internet to Ethernet and connect with cable to router. WAN is now working.

But remember to configure your WLAN Router.

Can no longer pick up router signal


Does the wireless light still lit on the router? You can try changing the channel on the router (1 6 or 11) ans moving the antenna. If those things did not work upgrade the firmware of the router and reset to factory default. Do not forget to save the configuration file before you reset to factory default.

Wireless router says its working laptop says no its not


Your sister was accessing the wireless access point at school which is connected to the Internet/WEB access via a router and the school's broadband service provider.
For you to access the Internet using your wireless adapter on your laptop, you need your own wireless access point and connect it to a broadband ADSL or cable modem and then connect it to an Internet Service Provider. Some Internet Service Providers (cable and ADSL) can supply a combined modem/router/wireless Access point.
If you already have a broadband modem all you need is a wireless access point/router. You only need to configure the wireless access point and your wireless adapter so they will communicate with each other. Folow the instructions in the manuals.

Wired and wireless computers


First get your router works with the internet on the wired connection before considering the wireless connection simplying the initial problem.

Once the router works wired is time to try the wireless.

Once the wireless works unsecured you may want to change the router and wireless adapter to secure the wireless network.

So this can be a three step process.

If you internet service is provided by a cable(tv) there is a reasonable chance your router will work out of the box no configuration changes. However, if your internet service is supplied on the phone line chances your router will work as it comes out of the box are much less. Who is your Internet Service Provider and if possible can you supply a link to their help/support website so I can see if they supply configuration instructions?

One thing that isn't mentioned anywhere is the modem has to be in bridge mode. I was told this by a Linksys tech after doing all that was documented in the references article. I contacted my internet provider and they told me how to set the modem to bridge mode. This corrected the PPPoE error.

Computer interfacing


You have a computer (what manufacturer and model?) connected to a Netgear WGR614 wireless router (please confirm the router manufacturer and model) by wire or wireless?

If the computer is connected wireless is it with a wireless adapter built into the computer or added to the computer?

If it was added to the computer what is the manuracturer's name and model of the add-on device?

Has any other computer ever successfully connected to the internet using your router?
  • If so was the computer connected using a wire, if possible?
  • If so was the computer connected wirelessly?
If no computers were connected successfully to the router please provide the name of your internet service provider?
I also may need to know the city and state you are located in or other information. We probably need to configure the router to attach to your internet service providers equipment

The following are to determine if the internet service providers equipment has been successfully installed and the capabilities of that equipment as it may support connecting your router, if necessary, and your computer to the internet.
Were any computers ever successfully connected to the internet by directly connecting to your internet service providers hardware?

If yes how were they connected
  • USB cable?
  • Ethernet Cable?
  • Wireless?
  • If wireless what is the manufacturer and model of the internet serivce providers hardware providing the wireless service?
