It seems that every time that I try a product intended to increase wireless range, I end up at the same place—uncertain whether it provides enough improvement to be worth the hassle and expense. So when PePwave asked me to try one of their Surf "Wi-Fi" modems, I wasn't in any hurry.
But the more I looked at the Surf, the more it looked like PePwave has taken a different approach. Actually, PePwave doesn't really pitch the Surf as a WLAN range expander or extender. That's probably because the primary application for the Surf series is as CPE (Customer Premises Equipment) for wide area Wi-Fi installations in (a dwindling number of) cities and campuses.
