TrendNet wireless adapter TEW-423PI is terrible. Drops connection every 5 minutes. Using with Windows XP and Dell Inspiron 530.
Company's website has bad driver and utility downloads and instructions are incorrect. Email to their company support (provided in their Read Me file) bounced (March 2010).
Stay away from TrendNet, unless you are a computer tech or shop that wants to make lots of money by charging your customers to fix problems :)
I can't believe this site really requires me to enter at least 100 words - so much for getting to the point. Well here are 100 words.
