Oceanside RCMP say wire thieves have been causing problems by targeting Telus communication lines in Nanoose Bay, Errington and Meadowood.
Internet and phone connections have gone down as a result.
Police said there have been five thefts or attempted thefts in the past 10 days by people seeking copper to sell as scrap.
