• No 5 GHz Wi-Fi (only 2.4 GHz b/g/n).
• No IPv6 firewall customization (basic SPI only).
• Maximum speed bottleneck – ADSL2+ tops at 24 Mbps, while modern VDSL2 goes to 100+ Mbps.

• Many researchers have documented how to use tools like Binwalk to extract the SquashFS filesystem from the firmware update .bin file.
• These analyses reveal that the J1 version runs a proprietary D-Link web server (goahead or httpd) and utilizes a specific Broadcom DSL chipset.
