I just got called over to my pet charity as they are have having issues with devices not connecting to wifi in the last few days.
When I got there my phone connected but had a ! for no internet.
Other devices were working fine, and some like my phone, just were not.
Their internet is via Spark Fibre and an HG659b router.
I checked the DHCP, it is set to 64-250 so that's plenty of addresses. The lease is 1 day.
Then I noticed the number of connected devices was 32. Exactly.
Is this the maximum allowed? If so, then totally inadequate for their needs.
Most devices however are transient. In/on for a few hours then out/off again. Only about 10 are on all day.
Could the situation be helped by dropping the Lease to 1 hour or 1 minute?
What happens when you do that? Do the devices that are on all day lose their connection every time the renewal comes around?
Is there anything else I can try?
