DELL D630 - CANNOT CONNECT TO INTERNET

Are you by any chance running firewall software that is blocking the internet connection?  Are you sure you are connected to the router?  As a troubleshooting step, can you connect to the internet if you connect using an ethernet cable to the router?  If you boot to Safe Mode with Network Support, can you connect to the internet?

 

To help troubleshoot this problem, on the computer with the problem, go to Start > Run and type cmd then click OK. In the command prompt window that opens, type ipconfig /all then hit the enter key. Write down the output from this command or select it and save it to a txt file, then copy this output into a reply to this message.

OK thanks, will do when I get home. I turned off Windows firewall. The PC has McAfee Security Center installed and within it, the "firewall" is stated as OFF. I tried connecting to the internet by plugging into the router and it was a no go the other day. Interestingly, when I went to "view available wireless networks" (normal wireless setup no direct router connection) I found an unsecured network in the area, clicked on it and it took me to the internet however, I've been unable since to duplicate that. I also tried disabling the WEP encryption on my router and it still will not get out to the internet despite being "connected" with good signal etc.

Volcano11 - OK, here goes: first, I tried connecting to the Internet in "safe" mode - no good, I have a wireless connection with good speed (54 MBPS) but cannot get to the 'net. Also tried with direct cable to the modem - same results. So, as requested, here is the result from my "ipconfig/all" for the Dell Latitude D630 which is not connecting to the Internet; hope it tells you something because at this point, I am out of ideas and so seems Dell, Verizon and Linksys!

 

As stated, I am using a Linksys Wireless G Broadband router (WRT54GL) connected to a Westell Wirespeed modem (provided by Verizon) which connects my upstairs computers (2) via a Linksys Wireless G Access Point (WAP54G) and an Etherfast Cable / DSL Router (BEFSR41). There are a total of 3 computers on the system.

 

Ipconfig/all result:

There are a couple of things in your ipconfig output that are of concern.  First it does not show your wired ethernet adapter at all.  Did you leave that part out?  Second, it appears that you have ipv6 installed.  Is there some reason that is present, i.e. did you recently install something that requires or thinks it requires ipv6?  If not, I suggest you remove it by following the instructions at:

 

http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/sag_ip_v6_pro_remove.mspx?mfr=true

 

Otherwise, the wireless is getting a valid IP address from the router.   If removing ipv6 doesn't fix the problem, try the following:

 

Open a command prompt window again and type the following commands:

 

ping dell.com then hit the Enter key.  Does it time out, or return 4 valid replies?

 

Then type:

 

ping 143.166.83.38 then hit the Enter key.  Again, does it time out or return 4 valid replies?

 

Next, connect an ethernet cable from this computer to one of the ethernet ports on the router.  Run the ipconfig /all command again and report the results.  Then, run the two ping commands again and report the results.

Steve:

 

Thanks for your reply. I did not leave anything out regarding the ipconfig/all report. As far as what is on the laptop, this laptop is from my job and I am using it mostly at home so what is or is not on it is how I received it, I've added nothing to the laptop since getting it about a week ago, except for Norton Systemworks and I only added the "utilities" portion not the anti-virus, etc. as it already has McAfee installed on it. The "job" I believe "images" these machines before distribution so perhaps that is why IPV6 and other things are on it. As for your instructions, I'll have to get to that when I return home again. Thanks.

Steve:

 

I followed the instructions on the link you sent me, however, I see NO reference to IPV6. I have two "local area connections" within the "network connections" window, marked "local area connection 2" and "local area connection 3" respectively. When I right click and go to properties, the only TCP/IP reference I see is "Internet Protocol (TCP/IP)". I tried pinging Dell.com and received this message: "Ping request could not find host dell.com. Please check the name and try again." When I pinged 143.166.83.38, I received 4 time-outs. The ipconfig/all command returns the following:

Any other thoughts?????

 

Now you have me confused.  In the first ipconfig output you posted a couple of days ago, the computer name (Host Name) was shown as  MD3467 and it clearly had ipv6 enabled.   You say that you cannot find ipv6 on your laptop, and the ipconfig output you just posted shows no ipv6 present, but also shows the computer name (Host Name) as Laptop. Were both of these ipconfig outputs from the same computer (It doesn't look like it).   I'm also still puzzled by the fact that only one connection shows up in the ipconfig output, and that no evidence shows of even having a conventional ethernet adapter.  

 

In any event, this one still shows that you are connected to the router,   The fact that you cannot get to the internet in Safe Mode eliminates such things as firewalls or malware blocking the connection.  So, if everything you have told me is true (i.e. no connection in Safe Mode, no connection when wired and no ability to ping outside of your network) suggests that the router is not making a connection to the modem. 

 

Now that I go back an look at your other posts, It appears that you have two routers on the network.  Is that the case?  If so, this could explain everything, as you cannot have two routers (both acting as DHCP servers) on the same network.   Of course this adds another bit of confusion to the whole problem.

This is the way the "system" here at home has been for YEARS. Why I have the equipment I have is because this was the way it was set up for me way back when. As stated previously, ALL computers have worked fine with the system as-is, never had any connection problems whatsoever. I believe the use of the etherfast cable / dsl router upstairs (initially) was to allow my kids friends to bring their laptops over and "plug-in" to my system via the router (this is before I became a little bit wireless saavy and now understand they could hook in wirelessly, if they have a card, etc. in their laptop). I guess this was just a way to ensure that if desired, they could use my wireless network. However, as stated, all previous computers have worked fine. I don't know that tampering with the physical devices currently supporting the system will make this new Dell laptop work. But, I am not the expert so, I defer to your knowledge and advice / suggestions. I am on my way to work now so, I'll log in later from there, to see what you have posted. Again, thanks for your assistance, regardless of how things turn out. You've spoken to me more than my colleagues, Linksys, Verizon and Dell combined! - Much appreciated!

Please explain why you have two routers on the network.  Only one of these routers will connect to the internet and if you are connecting to the one that is not connecting to the internet, then you will never get on the internet. 

 

Steve

Steve:

 

I appreciate your time - really. As I stated earlier, this is my system: Linksys Wireless G Broadband router (WRT54GL) connected to a Westell Wirespeed modem (provided by Verizon) which connects my upstairs computers (2) via a Linksys Wireless G Access Point (WAP54G) and an Etherfast Cable / DSL Router (BEFSR41). In playing with the laptop, I renamed it and may have made a few changes that altered the previous information presented to you - all unintentionally, as I desperately attempt to get this thing to work. Also, this laptop is "assigned" to me from work BUT - it is difficult to get someone (anyone) to spend time with me to troubleshoot this issue and frankly, when I discuss it at work, everyone tells me "hey, it's gotta work, it works here." It works when connected to the high-speed LAN at work (100 MBPS) but refuses to work on my wireless network at home. I am a novice with this wireless business and I do not know if there is something possibly missing in the laptop that would prevent it from reaching the internet. All I know is that it shows I am "connected" at a speed of 54 MBPS and in comparison to my other 2 computers, everything looks the same - it just WILL NOT touch the internet. I've gone up and down the scales with Linksys, Verizon, Dell and people at work and no one can figure out W-H-Y this laptop will NOT talk to the internet.

What is the purpose of the BEFSR41?  Is it set up in router mode or is it set up as a simple switch?  I'm guessing you have the access points upstairs set up to extend the range of the wireless upstairs.   Is you new D630 connecting via these access points or is it connecting through the WRT54GL?  If you take the D630 upstairs, near the access points, does it connect to the internet?

 

Steve

I just sent you a private message (you can see it by clicking on Messages at the top of the Dell forum) giving you information on how you can send me the screen shot.  I don't know if it will help, but it's worth trying anything at this point.

 

Since your network is working for everything else, I really hate to suggest making changes at this point.  But, one thing you could do is to put the laptop next to the modem and router downstairs, go upstairs and temporarily shut off the access points and the other router, then see if you can get an internet connection on the laptop downstairs.   This will simplify the network and perhaps give us a clue as to where the problem is.

 

Steve

Steve:

 

As far as I know, the BEFSR41 is acting as a switch (4 ports) to allow other users (visitors) to connect via LAN cable - of course, this has never happened since no one has ever come to my house with a computer, looking to "connect." The Wireless G Access Point is used to "ensure" a wireless connection to an existing Dell Desktop and this (new) Dell Laptop which are both used upstairs. Downstairs (in the basement) is where I am using my Gateway laptop which is connected to the WRT54GL Linksys router, which feeds off the Verizon Wirespeed modem. The new Dell laptop does NOT connect to the internet whether I am upstairs, downstairs or plug the laptop right into the modem!

 

Here is some interesting information. I took the laptop into Midtown Manhattan just a short while ago, to see if it picks up any "wireless" connections and sure enough, there were plenty to choose from. I chose one, connected to it and voila' - I am surfing the internet, no problems! So, whatever is wrong, is wrong somewhere in how my system is set up at home, be it the modem, router, cable / dsl router or wireless G access point. More puzzling is that ONLY this new Dell laptop has issues with the way things are - the existing Dell Desktop and existing Gateway laptop work fine, surf the net, etc. with NO issues. SO........ whatever is wrong, is germane to THIS new Dell laptop.

 

Just to provide you with as much information as possible, I am posting the "IPCONFIG/ALL I ran when connected to the wireless connection I picked up a while ago in Midtown Manhattan. I am also including a "screen shot" of how my "network connections" looked when I was connected thereat and ABLE to get out to the internet. Maybe ALL of this information can help you help me???? I await your review and further assistance!

Well, it won't let me "paste" the screen shot of the Network Connections. If you need to see it, perhaps you can advise how I can post it or send it to you for your review.

Steve:

 

STOP THE PRESSES! I solved the problem! Turns out that the router (WRT54GL) under the "DHCP Clients" panel had the "old" laptop's MAC address in it! I had to physically delete the old address and manually type in the new one. Once I did that and rebooted, I was "on the air" and flying on the 'net. Go figure. After seeing that I "can" access the 'net, I knew it had to be something in the router and the MAC addresses were the only things I did not check because I thought they were picked up automatically - turns out, that is not the case. So now, all is well for the moment and I am going to leave well enough alone and just enjoy it for now!

 

Thanks again for all of your assistance; it led me to where I went today and thus, the final solution!

 

Be well!!
