Hey. For the past few months I've been getting ping spikes of over 1000 ping for 1-2 minutes every 10-20 minutes. The main router is a bgw210 700 router with the firmware up to date (1.7.17). My electrician connected a netgear n600 router (wired to the main router) as an extender and I am connected wired to the n600. My ping is much lower but I still get the large ping spikes. Any tips? Thanks for the help.
