Not with VM currently. The FTTP installs are only happening in project lightning areas. And even then its still Hybrid, its just FTTP with a box to convert to Hybrid at your property instead of FTTC. ACTUAL FTTP is only available from a few providers and costs a pure fortune unless your in a block of flats that can split the cost. Basically because DOCSIS3.1 (coming soon,allegedly) offers FTTP speeds so why "upgrade"
The distance from the cabinet should not matter (Unlike BT's ADSL system). You could be up to 2Km from the opical node where the optical signal is converted to a RF signal and transmitted through an amplified coax cable to your local cab.
However, the greater the distance from your home to the cab, the greater the power attenuation (loss) will be, especially on the higher frequencies. So it would be worth checking the hub's power levels, when it is fine and when it rains.
It would be also worth locating the drop point outside your home (small metal cover stamped CATV) when it is raining to check for standing water. Water can get into the connector and degrade your signal,
Thanks for taking the time to post on the community.
Sorry to read that you are having issues with the broadband speeds when the weather changes.
I've checked your connection for any issues, the line and hub are showing as fine. The network segment is running stable and healthy. The router is showing as being online for over 125 days, so when you get chance a reboot will be helpful.
I can see that griffin gave some great advice in regards to when you notice the speeds drop check the power levels to see if they change at all. The power levels are currently showing as within range at + 5 dBmV, it will be interesting to see if these go any higher/lower when it does rain. What speeds do you achieve when you notice this issue?
