I have only had my captivate for 24 hrs so I am a newbie. I am not however a newtwork newbie. When I attach to my wireless network at home the first time all works fine. The second time I can not get to the internet and what I have found is my wireless router thinks my DHCP address is different than my captivate has. For instance, my router will say the captivate was assigned 192.168.1.4 when the captivate says the IP address is 192.168.1.5. The subnet mask and gateway is the same but the router is sending my traffic (192.168.1.5) to 192.168.1.4 since thats what it thinks it is. I used a program called wifi static to manually specify my address and I have yet to have an issue but this is a concern. It could be localized to my network but thought i would throw this out to see if anyone else has seen any similar issues.
