4g coverage SW Lemu problems.

Elisa saves energy by turning some of the high frequency bands off during the night. Typically this is 1800, 2100 or 2600 MHz. Low frequency bands 700 and 800 MHz should not be affected. Depending on the equipment used at the basestation, this is done either by a timer or dynamically based on the amount of traffic the basestation gets.

Have you locked your router to a specific frequency band? Try leaving band selection to auto and see, if this settings works for your location and equipment.

If your location has heavy use during night, 700 and 800 MHz bands may get congested and your connection speed may plummet.

Some routers may have problems finding the high frequency bands again in the morning, thus getting stuck on congested low frequency bands until a reboot.

If you have a narrow bandwidth outdoor antenna, you won’t be able to connect to frequency bands your antenna does not support.

Should you have any of the last three mentioned problems, send a private message to user OmaYhteisö-tiimi on this forum or contact the customer service. They can disable power saving at your location.
