My 5g router went low speeds in my area due to an "issue" in my area 7 days ago
2 days ago i called three, they gave me 5 pound bill credit for the issue and said call back if the issue persists after 2 days.
Today my wifi went from the horrendous 0.5mbps down and 10mb up
To 300 down 40 up
Rare thing on this forum to say something good about three
Still was a pisstake to have horrible wifi for 7 days
