Error Codes Wan005 and Wan002

I should've stayed away after reading the reviews. Now I regret getting T-Mobile home internet service. Phone service is fine but home internet is horrible. Constant buffering (frozen now as Im typing this), bandwidth is low messages, "no internet connection" message even though the router shows 4 Bars with "your connection is very good" message. Most recently I've been getting WAN002 message. Too bad I've already paid my bill for this cycle but I'm going back to Spectrum before the next billing period. $30 bucks a month for T-Mobile home internet is certainly not worth the aggravation. Spectrum is most definitely worth the extra few bucks.
