What replaces the Cisco C819HG-4G-G-K9?
Cisco's recommended migration is the Cisco Catalyst IR1101 Rugged Series Router (IR1101-K9). Uniqcli, an authorized Cisco partner, can quote the replacement TAA-compliant and GPC-payable, and help plan the cutover.
Can I still get support for the C819HG-4G-G-K9?
Not from Cisco. The C819HG-4G-G-K9 passed its Last Date of Support (Dec 31, 2021), so Cisco TAC, hardware replacement, and SmartNet renewals are no longer available. Independent third-party maintenance can still cover the hardware itself, typically well below OEM renewal rates. Uniqcli can review your install base, confirm coverage, and quote extended support or a refresh side by side.
