GNex Buyer's Remorse

Hey guys,

I just received my GSM Galaxy Nexus in the mail today, and I'm not sure what to think. I have not received my sim card from Straight Talk yet, so I'm only basing my thoughts off of wifi, which brings me to my biggest concern: wifi signal.

I immediately noticed how weak the signal is. I've been using a Moto Triumph through Virgin Mobile, and have had perfect wifi reception in my room. Today, I booted up the Nexus and I can't even stream youtube videos without contant pauses for buffering. It updated up to ICS 4.04, so it shouldn't be a software issue, correct? Does anyone else experience poor wifi signal? Should I return it for another? I really don't want to pay the 15% restocking fee ($60) and go back to my Triumph.

Thank you.
