ICMP packets not working on Dell Latitude D620

I have a Dell Latitude D620. I have AVG as my anti-virus software and Windows Firewall as the firewall. I am using Windows XP SP3. I work a lot with Cisco equipment and I need the ability to TFTP from my laptop to Cisco devices. The problem I have is when I try to PING my laptop from a Cisco device (ASA firewall, router, switch) I cannot ping my NIC (Broadcom NetXtreme 57xx Gigabit Controller). I can ping the Cisco devices from my laptop without any issues. Because of this, it is preventing me from being able to TFTP Cisco IOS images and files from my laptop to a Cisco device.

I have uninstalled my network adapter and had Windows discover and install it again. I also have updated the BIOS (A10) and the NIC driver to the latest driver on Dell's website. I have uninstalled my previous anti-virus software (Trend Micro OfficeScan) and switch to AVG but still to no avail.

I'm lost as to where to go next. I don't want to reimage my drive.

Any help would be greatly appreciated!

Thanks in advance,

    Right now I am directly connected to my Cisco ASA 5505 firewall via one of the Fast Ethernet ports. I also am connected to the console of the ASA firewall. I won't need to run a tracert because I am directly connected to my ASA firewall. When I am on the console and I issue a PING command, the result of the command is an "unknown packet type" is returned.

    Have you tried Tracert to find out where you are losing the connection? Also, have you ping, to test your NIC...because it sounds like a networking problem as opposed to any type of hardware or software problem. Are you sure that ftp port number 21 is open on the other end? Just some suggestions..let me know.

With vista I had the same problem, but when I enabled network fileshareing and set up some network drives it started to answer on ping requests, so it should be one of the networking protocols to enable.

My Dell Latitude D620 is constantly spiking at 100% cpu, the problem arises especially when running the mouse over any program, it basically locks down my whole computer and nothing will run, it always...

It sounds like there could be a virus on your computer that is using up all of your CPU resources. Try to monitor the processes and CPU usage, buy pushing Ctrl + Alt + Del at the same time. This will open up the Task Manager on XP, or show you a menu screen on Windows Vista and 7, and you can click on start task manager at the bottom. View all your processes and how much cpu usage is being taken up from those processes. Look for the process using the highest cpu usage when it spikes to 100% and please repost the process name!

In the mean time might I suggest running and anti-virus scan, scanning for malware, and spyware as well. If you do not have any of these programs, I would suggest using either AVG, or Avira Anti-Virus, Malwarebytes, and Super Anti-Spyware, all of which are free programs that can be downloaded here!

How to edit configuration .ini file to stop avg turning firewall off

If your avg is AVG Anti-Virus plus Firewall Edition, then you should not be running Windows Firewall as running two firewalls can cause conflicts and for sure adds an unnecessary extra load on your PC. This also applies for trying to run two anti-virus products together. Besides the extra load, the conflict can bring the PC to a crawl.
