On Mavericks, my laptop had issues on my home wi-fi, an old WRT54G Linksys router.

Tips:
- change DNS servers to google DNS 8.8.8.8
- set MTU size to 1453 (refer to OS X Daily article)
- reset Chrome (disables all extensions)
- considering changing home wi-fi radio channel if using 2.4ghz bluetooth devices
- disable bluetooth devices and see if it makes a difference (this appears to be the main issue for me)
