I have a location with a DSL internet connection and an Actiontec PK5000 router. Sometimes customers call and ask us to process a credit card for them using our internet connection. We also have a DVR at the location and we need to access it using its ethernet connection. I could not use port redirection for the DVR and have an active firewall at the same time on the Actiontec. I purchased a Cisco E1200 router, converted the Actiontec to be just a bridge and want to use the Cisco router exclusively. When I hooked it up I used a Panasonic laptop with W7 and the configuration went smoothly. I then plugged in the IBM Think Center desktop with XP and the problems began. The desktop has a Broadcom NIC and I am able to ping locally and outside the facility with no problem. But it does not browse. The browser bar sits there trying to make a connection but nothing happens. I tested with the laptop and both the wireless connection and the NIC work properly. I took an identical machine to that location with identical results. I put a Linksys 10/100 NIC in the machine and tried, but again no connection. I have a Linksys USB wireless adapter and plugged that in and it seemed to work well for a few days.
Right now things are not working well. The ethernet wired connection is not working so we are relying on the USB wireless. But sometimes it is taking a long time for that connection to be established. We are rebooting the computer and routers almost daily and having problems. Sometimes even local connections to the DVR can take an hour or so to establish. I have LogMeIn remote access loaded on that computer and I can connect to it quickly but I still have trouble browsing. It makes no difference using IE, Firefox or Chrome as the browser.
I am running a software at this location which will not run on W7 but requires XP. I do not know if XP is the problem or if it is something else. I am tempted to try a low end W7 computer and if it works get a KVM switch. But any ideas anyone may have would be most appreciated.
