distance you can place cisco 1041n from 881

We have an older building that has no overhead access there are tunnels underneath the building so to get a cisco 1041n to the other side we had to go up one side of the building then across the building then all the way down the other side of the building making it 350 to 400 feet from the firewall. We haven't read anything on how the distance may effect the signal as the 1041n show good strength but the download speed is below 512k. Any thoughts would be appreciated.

The limit for cabling between active devices (a router or switch, for example) is 100 meters (about 328 feet). Obviously you won't have total failure at 101 meters, but the longer you go past that, the more your transmission will be slowed and eventually not work at all. So if you are running 350 feet the distance could be a problem, and at 400 feet, you are really pressing your luck.

One possible fix is to insert an active device (a simple switch) somewhere in the middle so that no run is longer than 100m. If your 1041n uses Power over Ethernet (which they typically do), make sure that you put the power injector in the last run before the 1041n, since most switches don't do PoE.

If you could see the metrics at the router, the way you'd see if you had a problem was in the packet loss counters. I suppose you could call GSC and ask them to look into your router and tell you what they see. If you are getting any packet loss, you will start slowing down because the device is having to try multiple times to get the packet back to the router.
