[wireless]

i just had telus installed my internet 75. The modem/router is T3200m ver 31.164L.18. My wifi speed was ~ 65mbps...i can live with it. But the following day, wifi was varying between 30 and 45 mbps and has never gone back even close to 55mbps. I connected (hardwire) my laptop directly to the t3200m's lan port 1 ...speed is perfect at 80 to 83 mbps! So i was suspecting the router part of this modem is not stable. Do you think i can solve this problem by buying a separate router? I have an Asus RT-N12-D1 router that i use when i was on 25mbps. I connected this router to the T3200M modem and checked the wifi speed... it reads around 50mbps consistently , tested for at least 5 times every 5 to 10 minutes interval. Any suggestion which affordable router i can buy that can handle "actual" speed of >=100mbps ? or any suggestion what to adjust in this modem that can increase my speed close to 75mbps? thanks
