We have a Netgear WNDR3700 Dual Mode wireless router. I connect to it in 2.4Ghz mode usually. The 5Ghz mode also works without any problems.
Wireless at work is handled by Cisco access points which seem to hold the connection well. The network is designed as a 'guest' network for use by smart devices and vendors with wireless laptops etc. and provides a connection directly to the internet. The downside of this is that there is web page where you have to log into the network to get access (similar to McDs). Sometimes this connection expires and you find that you have to log in again to get the connection. No problem really, a heap better than it was a year ago!
Overall I can't complain about any wireless issues. Has a slightly better range than my Desire did and connects at 5Ghz.
