This is a general notice to ONT(Fiber) ISP service users only!
Some ONT providers may not be compatible with the DGL-5500 at this time. Some users may exhibit slower speed rates on the router than what they should be getting from there ISP when checking speeds. There is a compatibility issue that D-Link is aware of with this type of ISP provider service. We hope that the issue will be corrected soon. Inflammatory posts will be removed!
Please be patient.
For users with ONT ISPs, please post here with ISP service name, ISP ONT hardware Mfr and model information. D-Link will need this information to help troubleshoot the problem with this router and ONT ISPs. There are many ONT ISP providers so HW and configurations are many and vary. D-Link may ask users with the DGL-5500 to help capture data packets using Wireshark, when connected to the ONT service, to review for problems and help resolve them. Please follow forum policy when posting please.
For ONT users with this router model and are experiencing this kind of problem, or not willing to post in the forum, we recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.
Thank you.
