StandBy sometimes breaks DNS (XP)

Thanks to John Navas for his previous help with this issue:

Losing connection (Computer->Wireless->Router->DSLmodem)

I removed the SBC Yahoo DSL software and things seem better. I still sometimes have a problem when my notebook returns from StandBy. It looks to me like it's some issue with either XP (most likely) or the router no longer having the ability to do correct DNS resolutions. Here are the details:

- I can get to my router (since I use the IP addr); it seems to be able to ping and trace all addresses using either IP addr or host/domainname

- FireFox and cmd line (ping, ftp) won't let me get to anything unless I use the IP addr

- today I tried for 30 mins to fix it before rebooting (and then things worked fine again)

Here's what I tried (some multiple times):

ipconfig /all, /renew, /refresh, /displaydns, /flushdns, /registerdns nslookup nbtstat -R

I also tried going into the network properties and entering the IP addr for dns.sbcglobal.net as the DNS server (and refreshing everything) but it still wouldn't work.

I wonder if it is related to either of these:

How Internet Explorer uses the cache for DNS host entries

(I would have tried the cmds in the second one but I couldn't access the article while it was broken.)

Any other thoughts? Thanks!
