We have found that a surprising number of inexpensive home office routers shipped in recent years with buggy software. They often work fine for typical web browsing (which mostly downloads data), but intermittently fail when hosting a Glance session (which uploads heavy bursts of data).
If your sessions repeatedly drop (especially if this happens some minutes into a session) and you connect through a home office router, make sure the router has the latest software. Check the manufacturer’s support page: Linksys, NETGEAR, D-Link. If there’s a newer version, use it! Contact us if you need assistance.
