Something odd here , if this is a newly installed FTTP network, for some illogical reason the checker shows upto 330Mb as the maximum speed and that is synonymous with first generation ECI equipment from 10-15 years ago ….if this is an error setting these parameters on the checker (it almost certainly is a records issue they won’t have installed old equipment ) then automatic systems that use this incorrect data will error , if 330Mb is the incorrectly set limit , then any speed above that will not show as available, which may be why the agent says 100 Mb is all that’s available (which is actually 150Mb but strangely sold as Full Fibre 100 )
This error may get resolved automatically if this entry has only just appeared , so waiting a day or two may see the correct speeds showing , unfortunately explaining this to an ISP customer service representative probably won’t be of any use , they are not likely to understand and even if they do , they can’t do anything about it , and you raising this issue with the appropriate people, if it doesn’t resolve itself , may not be easy .
