Strange trace, funky happenings on my network

First, let me explain my network ... 2 comps in my room connecting to a Netgear 4-port hub. Netgear 4-port hub connects to Kingston 8-port switch. 2 comps, a printer, a Linksys BEFSR11, and a Linksys WAP11 also connect to Kingston 8-port switch. Linksys BEFSR11 connects to cable modem, Comcast is the ISP. 1 computer connects to the WAP11 at the moment. The BEFSR11 is doing DHCP. All systems are running Windows XP.

All of the computers can get onto the internet just fine except for the one that connects to the WAP11. I figure this is a WAP11 problem since the thing is a piece of shit. The laptop gets all of the proper information (i.e. IP address, DNS info, etc.) but cannot resolve any DNS. I did an ipconfig /flushdns and it can resolve names if I use the nslookup command, but it cannot ping anything and says that the hostname cannot be found. I told the system to use my workplace's DNS boxes as primary and secondary DNS, and that works flawlessly. Why isn't the laptop allowing the Comcast DNS boxes to resolve names for it?

Furthermore, here's a trace from my system (but it could be any of the systems, since they all do the same thing) to Google:

Why does my trace look that strange?
 
Nobody? I'm still getting that funky-ass trace ... the rest of my network somehow fixed itself
 
First off, the tracert looks like snmp packets are not being forwarded, but I'm not sure. Check your WAP setup on that.

I'd say that your dns suffex on the pc may be wrong. For instance, I have to add insight.rr.com to all computers for dns to properly work. Try adding in your isp's domain name in the TCP/IP > DNS properties under the DNS suffex and see if that helps.

All systems have a trace like that, regardless of whether they're connected to the AP or not.

I added the DNS suffix to the connection in all possible ways (it's XP Pro, there are a lot :p), and it still didn't do it. Looks like I'll be stuck with the shitty trace indefinitely :p
 
Could the issue with the laptop be Spyware related? Have you run Spybot and Adaware on it to check. You could possibly have some sort of malware on it that set up the TCP/IP stack with a hidden proxy that it messing up your connection.
 
The laptop with the DNS problems is off at the moment. There is another laptop, my own, which recently had an OS re-load and is currently used for Folding. The rest of the systems (Shuttle SS50 and 2 other systems that I built) are having the trace problems.
 
I don't understand what you think is so strange about that tracert?

Notice how the middle column consists entirely of * characters.

Here's a trace that I just did:

Notice the stars present in the middle column. I don't understand why it's doing that.
 
Ah. Ok yeah it's strange that the middle ICMP echo request packets consistently get "lost". As a pure guess, I would say the middle echo request is a different ICMP packet type than the other two? And a firewall on your end (or your ISP) blocks that particular type of ICMP packet.
