do you mean to imply your ubuntu machines share a common connection to the outside world with other machines that are working better? perhaps there's a subtle difference between configs, like ubuntu might direct dns via the modem, perhaps others go more directly to the nameserver. sounds likely that your dhclient is functioning as expected. can you ping your modem? can you ping the outside world? can you ping the nameserver? are you able to resolve or pull up some names/pages but not others? can you ping the ones that don't resolve? wouldn't be the first time an ISP's nameserver wasn't functioning up to snuff, i've sometimes run my own for that very reason. dig is a good utility, or even "host" will be helpful, point either at the dns server, can it resolve various domainnames? does it work when you point dig/host at the modem? if iphouse is your isp, they're usually pretty knowledgeable, friendly, and helpful....
