Daily huge lag spikes / internet drop across all devices

Hi All,

Currently have a full fibre plan having switched from TalkTalk with 2 years of not a single problem - I don't think my internet dropped once in that period too!

I have been with Vodafone now for close to 2 months and this issue has been happening ever since, it will be completely random throughout the day and will be a 10-20second lag spike (at least I think its a lag spike) as everyones device just buffers/freezes or disconnects (streaming, gaming etc).

The latest 'spike' happened just now at 17:27.  I am absolutely useless in reading logs but can anyone identify what's going on?

Thanks,

@Mull1t For starters turn off IPv6 everywhere and see whether that makes an improvement. Also have you done a factory reset yet?
