Is the GXP1782 the same as the GXP1780 with Wi-Fi added?

Exactly. Same body, same screen, same SIP capability — plus a dual-band Wi-Fi radio. About $15 more.

Does it support Wi-Fi 6?

No. The GXP1782 supports 802.11 a/b/g/n (Wi-Fi 4 on 2.4 GHz, Wi-Fi 4 on 5 GHz). For Wi-Fi 5 support, the modern GRP2614 / GRP2615 are the equivalent. For Wi-Fi 6, the GRP2616 / GRP2624 / GRP2634.

Can it do both Wi-Fi and ethernet?

Yes — Wi-Fi is a fallback / alternative to the ethernet port. Configure either one as the primary network from the web UI.

Will it auto-provision over Wi-Fi?

Yes, if Wi-Fi credentials are pre-loaded. We can do that before shipping if you send us the SSID and password during onboarding.

Why the GXP1782 is on the catalog.

The GXP1782 is the GXP1780 with a dual-band Wi-Fi radio added. Same chassis, same screen, same 8 lines, same 8 keys — but you can put it on a desk with no ethernet drop and it just works. About $15 more than the wired GXP1780.

Where it makes sense: any deployment where one or two desks in an otherwise-wired fleet need to live without ethernet. Conference room phones (where the room ethernet drop is on the wrong wall), back-of-office desks that were added after the original cabling, executive home offices on a corporate VPN over a residential Wi-Fi. The 5 GHz band is essential here — 2.4 GHz is too congested in any office environment for reliable HD voice.

Modern equivalent: the GRP2614 (16 lines, 4.3-inch screen, Wi-Fi 5 + Bluetooth built in, USB, GBX20 sidecar, similar price) is a substantial step up. For new Wi-Fi-capable deployments the GRP2614 is almost always the right call. The GXP1782 is the right pick for extending existing GXP fleets where Wi-Fi was added later, or environments specifically standardized on the GXP1780 chassis.
