  1. Broadcom is ushering in a new generation of Wi-Fi technology with the release of its first gigabit-speed 802.11ac chips. The company says the new chips are aimed at enabling higher-bandwidth…

    But wait, doesn't that mean you'd need a new wireless card in your PC/Laptop to get these speeds? So even if your router had these new chips you'd need an adapter that is capable anyway?

    I wonder if these will increase range though even on older adapters?

    Hmm... good and bad. Wider range does not necessarily mean good thing. Many (including my neighbors) tune their routers to transmit at high power (longer range), which is also the default for most routers. That translates to more interference because only one device can talk on the same channel at any one point. That is why we should set our routers to the lowest transmission power as your setup or location allows. So, contrary to common sense, lower transmission power could actually mean higher throughput (TomsHardware has a great article on this subject).

    I'll buy another router or wireless card to handle the boost... Give me more POWAH!

    @burty117 I imagine that yes, you will need another adapter in your laptop/pc to achieve the higher speeds mentioned.

    I'm not sure what you mean by your 2nd question though. I would think that if you had an 802.11ac router, regardless of what adapters you had in other devices, they would be able to take advantage of the 40-60% range boost mentioned.

    great... just when i finally upgraded to 450mbps N Airport Extreme with triple radio band.

    Maybe this one will finally be good. I tried wireless N for about a year before I finally got frustrated enough to just run a 75' cat-6 cable. I needed the signal to go diagonally about 35' through a floor (nothing special about the floor, normal wood and carpet) and it simply wasn't good enough for streaming video. Even espn3 wasn't able to sustain high quality (when on wired it did just fine), added another wireless router for G speeds (different reason why I added that) and would connect to G and get slightly better performance. Still not acceptable though. Wireless routers used: wrt320n, wrt54g (with ddwrt)

    Maybe this new standard will change things, but I think the rule, until proven otherwise is: always use wired unless there is no other option.

    Very similar experiences to yours SNGX. Wired is king when you need a fast and reliable connection, even more so for streaming.

    Agreed, having to reset the adapter for my computer every couple of days is annoying, which is something I have to do for wireless (might be a driver/config issue though), but the good ol' wired connection is rock steady as expected.
  10. I think I'll wait until the wireless industry ratifies the final standard. I can't stand having to use yet another emerging standard, and then finding out later your products doesn't meet a certain criteria, so you have to buy yet again. We have enough "preN" paperweights already, no thanks.

    I have to use wireless in my uni accommodation and while its great 100Mbps download and 50 mbps upload- consent no matter what time of day, every now and then the wireless just drops. Its a block of flats so maybe its someone using a microwave in the building or something, but highly frustrating when in middle of a Match on the PC/ PS3 or watching something on the BBC Iplayer and it cut out or give me the "Insufficient bandwidth to stream program"
  12. 40 to 60 percent better range = 40 to 60 percent more piggybacking
