However, as of May-2010, the routers are connected to 100 Mb/s network switches, which means you won't see the maximum wireless speed. For now, the choice between the flavors is largely arbitrary; however, the 2.4G signal strength will probably be greater. | |||||||

The purpose of this arrangement is to make it easier to find out which wireless router your laptop is using. For example, if your laptop has been assigned the IP address 192.168.5.4, then it's getting its wireless signal from the router at 10.43.2.5 = wireless-library.nevis.columbia.edu , the wireless access point in the Nevis library. | |||||||

The routers in the mansion house are older model, and have separate 2.4GHz and 5GHz network names. You may have to try both versions to see which one suits you; the 5GHz network is faster but its range is smaller. |

Wireless routersAccessThe Nevis particle physics group maintains several wireless routers throughout the upper portion of the Nevis site. They are all protected by an access code:higgsino
The code is given in clear text above because it's not meant to block out anyone with a serious connection to Nevis; it's meant to block use of the networks by Nevis' neighbors or strangers sitting in the Nevis parking lot.
