Restart the computer. Now keep tapping the F8 key. Wait for the Windows Advanced Options Menu. Using the arrow keys select Safe Mode with Networking press enter. Once the computer is in this mode try to connect to www.Google.com only. Do not surf in this mode. This mode will run with no Anti Virus and Firewall running and may determine if those programs could be an issue.

Let us know if you can connect there.

There's a lot to read in your post. I see you connected at your nephew's house. So my advice above maybe useless. Give it a shot though.

zep516 - has anyone ever told you, "you are a genius"? If not, they should and I'm certainly telling you. This seems to have worked. I am sitting here at my desktop with my new laptop connected wireless - having followed your instructions. Now .... what does all this mean and how do I resolve it? I do have Panda antivirus installed on my desktop, so is that the problem? I told them at the computer store to install the same on my new laptop since I had another installation of Panda. I know on the desktop the windows firewall is disabled and the Panda firewall enabled - is that the conflict? I cannot thank you enough for at least getting me this far and gotta tell you I have no doubts you'll get me all fixed up. THANKS!!!

You might consider resetting the Dlink router to it's default settings and see if it connects.

Google Reset dlink to default setting.

Have to go the Vet with Annie Dog, let me get back to you.

What I'd like to do is consider getting rid of Panda on Laptop it's huge program. Then installing Microsoft Security Essentials or Avast both programs are free, That's a choice you will need to make. The windows firewall should be ok if the new laptop is Windows 7 or Vista.

Unless we can find the conflict

Hey Zep - hope Annie is well and that your trip to the vet was just a check up.

I'm actually just now getting back online. The reset of the D-Link router didn't help and actually seemed to confuse my old desktop as I couldn't get any internet connection after the reset, but then I unplugged everything and let it 'rest' a while hoping I wouldn't have to call Comcast back. So, I am now back online with the desktop, but can't get anything to connect with the laptop - previously I was able to get the laptop to connect directly to the modem. Oh well. I'm losing track of what is doing what and when.

In your last post you said "What I'd like to do is consider getting rid of Panda on Laptop it's huge program. Then installing Microsoft Security Essentials or Avast both programs are free, That's a choice you will need to make. The windows firewall should be ok if the new laptop is Windows 7 or Vista."

I do not as yet have Panda installed on the laptop, it is on the desktop and I had requested that they install it to the laptop but they didn't. So, looks like that's one good thing, huh? And the laptop has Windows 7 - so I'm understanding you to say that it should be o.k. with the windows firewall? And that I can just install one of the free antivirus that you've suggested?

Now, back to the laptop's issue of not connecting to the internet. I did finally get to speak to the guy at the store where I bought the computer. He said the only other time he's heard of an issue where one computer trying to connect to the internet caused another to disconnect was with a client that their router was not issuing an ip address to the new computer. He said he'd like to help but doesn't know without coming out to the house to actually look at the setup and of course I'd have to pay for a house call. Which I totally understand because I do not think it's an issue with the computer since it did work at my nephew's house.

Now, I'm down to deciding whether or not ... to pay for having them to come set up my network at which time I'd get an education in a lot of 'how to' and I'm thinking I'll end up buying a new router anyway (he said the tech would bring one with him in case he couldn't get my computer going with the router that I have) OR just go ahead and buy a new router and learn here on this computer forum from generous folk like you. If I should choose to buy a router, he said the one they sell is a "Netgear" for $49 - do you have an opinion on that or other recommendation?

Thanks AGAIN, and hope all is well with you.

Frances

I think I might try going into your router settings page using that address you mentioned previously and in the options to set up security try adding the new laptops MAC address there. It could be that when it was originally set up it was set up using MAC addresses.
How to find your MAC address in Windows 7?

this link to the Dlink router wizard may help
D-Link Router

some general instructions on using MAC address filtering, if you go into your settings and do see the MAC addresses in there for your other computers then you know your router was set up with MAC address filtering and you will need to add the MAC address of the new laptop to the list so it is able to connect.

Filter MAC Addresses
Step 1

Click the "Advanced" tab in the D-Link "Configuration" screen and select the "Filters" button.
.
Step 2

Choose the "MAC Filters" and click on "Only Allow Computers with MAC Address Listed Below to Connect to the Network."
Step 3

Enter the name and MAC address of the computers allowed to access the network, beginning with the one you are currently configuring. Click "Apply."

Your situation is very strange, the fact that when you try to connect with it that your other computers lose connection is weird.
All the simple things, make sure the wireless button on your new laptop is fully turned on, since it is often a slider sometimes it gets partly turned off.
You have set up and entered your passphrase into the new laptop for your secured wireless network.
You are working in close range of the router with the laptop.

very first thing I would suggest trying is a full power down sequence as below, then check the other stuff I mentioned.

try a full power down of everything, all computers and laptops, router, modem everything powered off. Let set at least 5 minutes then power up in this sequence which is important, power up the modem> let it get fully lit up (do not rush through this) once it is fully lit and blinking then plug in power to the router> let it get fully lit same as the modem, next power up the new laptop and see if it will find and connect, of course you may have to enter the passphrase for your network, then power up the desktop and any others, if this does not work do it all over again but next time power up the main desktop first then the laptop. Is the desktop hardwired? IF still not working try it with the laptop hardwired to the router on the power up.
It seems like the laptop is not getting the IP.

A flush may help, lets try those things first and see.
Zep will probably have some more ideas also.

You said you do not have Panda on the laptop, did the laptop come with an antivirus suite preloaded and if so what is it? if not does this mean it has no antivirus at all on it currently?

Please give us the exact model number of your dlink router look on the bottom.

"uninstall Lenovo Readyconn"

Seems to be the solution to this problem

link below..

Paddy...

Here is a link that might be useful: link

Annie! very high maintenance dog. Newfoundland.

I'm losing track of what is doing what and when.

I could not agree more, after all of raven's suggestions I would be out of ideas here.

I thought we had it with the Safe mode networking thing.

My only next thoughts were to reset the router to default settings.

After that I'm not sure!

Sometimes you have to know when to hold them and when to fold them. Calling for help maybe best.

Sorry paddy

Did not see your post. Nice to see you here.

From reading what I've read on other forums !

It seems to be a software problem that came with the laptop read the link see if it helps...

Paddy..

Hey Padd_y good to see ya! And great find on that link! Sounds like a real problem comes bundled with that lenovo.
they really should have put out some info on that problem so customers would be aware of it.

Hope this is the solution here

Zep I did not know y'all had a Newfie! they are such neat dogs. Know a few of them pretty well LOL

Thanks for all the suggestions - I tried looking at the "Filter MAC Addresses" and not sure I am understanding - but I went to the web address for the router and found the place where you can select the option for "Only Allow Computers with MAC Address Listed Below to Connect" but that option was not selected and no addresses listed. So I didn't feel comfortable setting it up as opposed to adding another address if there'd already been some listed there. I did follow the instructions for finding the address on the laptop but the number looked a bit strange - just a bunch of zero's with an alpha character at the end which made me think maybe I hadn't found the actual address and of course that made me hesitant about adding to the router for fear I might foul up the 2 computers that are working correctly.

I did try the 'flush' and powered everything back up in the sequence you gave me but same thing, and then had to do it again in order to get the 2 original computers back online.

So now, I am debating the uninstall of the Lenovo ReadyConn - I may try that when I get the courage.

OR I've been thinking that I might just be better off buying a new router. The one I have is 3 years old - if it's old for a router, then maybe that is my best bet and hope a new one will fix my issues.

I can't thank you enough for all the help you've given. I'll keep working with this and trying and re-trying as I have time over the next few days. If/when I get this resolved I'll let you know what I've come up with.

Thanks again for taking the time and making the effort to help - it is a great comfort to those of us that so desperately need it.

Frances

I would go with uninstall of the ReadyConn since it seems to have been the critical component in so many other similar problems.
Please do keep us posted and good luck

Hello and thanks to everyone who contributed info for troubleshooting my wireless connection issues. I am happy to say that after much dispair and a lot of anguish this message is coming to you from my new lenovo laptop that I am FINALLY able to get online with.

I was worried about 'uninstalling' anything to do with a new computer for fear of really fouling it up, BUT finally decided I'd try it. Well, Lenovo ReadyComm was indeed the cluprit! Although the computer was able to get online with at my nephew's house with his linksys router, evidently my D-link (an older one) router just did not like that program. I can not thank you all enough!!! there are just not words to adequtely express my graditude. I bought the computer from a local computer shop thinking I'd be able to get 'support' in the event of any problems but nice as they are they were no help for this situation. Anyway - after the uninstall, it was a breeze getting on the internet and the other 2 computers are also working fine.

Would love to do something as a 'thank you' - any of you have any interest in plants? I occasionally trade plants here on the garden web - if there'd be anything I could send you it would do my heart good to be able to do something nice for you folks. Just let me know if you have any interest.

Thanks again!!!
Frances

oh I am so happy you got it all worked out, what a great find that was about that program causing the problem, you would think the manufacturers would send out some warning about that or at least post it on their site.

You are so kind to offer your plants. I need to start visiting the plant forums, since we moved here to the new house in the Woodlands area of Houston I have been working on establishing a few plants, everything here had totally died from the heat while the house was on the market and no one was here to water. One thing I planted is going like gang busters that is a lime green colored sweetpotato vine, it is beautiful but very invasive, my other plants in my front bed are losing ground to it LOL.

ravencajun - I'll be looking around the house/yard to see what I have that I'd be able to ship when it cools a bit, and I'll make a list. If you're interested send me an email.

Frances

Great news! Glad you got it.
