Can ping but can't surf

I've seen posts that are similar but not exactly the same situation, so here
goes:
I have a wireless router for my desktop (wired) and my new laptop. I can
surf without problems on my desktop and my laptop when it's wired. But when
I try to surf wirelessly on the laptop, no luck. I can ping both ips and
urls on the laptop wirelessly. I also took the laptop to a coffee shop with
wifi, and I was able to surf just fine. So I'm stumped. I have seen some
posts that hint at a winsock problem, but why would it work in the coffee
shop or when it was wired? Seems like it must be a router config issue, but
I can ping everthing, desktop, router, outside world. It's not a DNS issue
because I can ping urls. Any ideas?

Two new pieces of info:

1) the problem seems to be related to packet size. If I ping with a packet
larger than around 200 bytes, it fails, whereas my desktop doesn't.
2) I was able to try it on another wireless network and it doesn't work
there. So the only wireless network that it worked (the coffee shop) was an
11g network, whereas the two that didn't work are both 11b networks. My
laptop's internal wireless is supposed to be compatilble with 11b and 11g.

There may be a setting in the laptop's wifi adapter configuration
utility that sets it to g-only or mixed. This is definitely the case
for wireless g routers, but I can't recall if I've seen such a setting
for wifi adapters. You probably will have to use the configuration
utility from the laptop/wifi mfr for this.

After mucking with it some more, turns out that if I set the wireless driver
to use "11 Mbps" instead of "best rate" that solves the problem for the 2nd
11b network. As for home, that still did not work. I tried an older 11b
only pcmcia card for the laptop at home and that worked. So seems like some
incompatibility between my built in wifi and various wifi networks. BTW my
laptop is an hp dv5000 model, the built-in wifi is a broadcom.
