Just wanted to tell you that the S415 that i purchased on Tuesday 02/11/14 had the same issues. I downloaded the newer driver. uninstalled the old one, then had to manually install the new onw and its been good ever since. Thanks, now if someone could have told me that the Y560 i5 boards didnt support the i7 quads then i wouldnt have wasted my money on a I7-820qm
Funny the tech did tell me that the board in my Y560 would support the cpu, even went so far as to look up the serial number (

First, thank you for answering so promptly.
I tried disabling upnp but I still could not connect. I should have been more clear in my description of the problem, however, so apologies. My router is a Ubiquiti EdgeRouter Lite. The Linksys EA4500 is only functioning as an access point. Linksys offers a 'Bridge Mode' setting for this purpose. While in this mode, the DHCP server is off, the firewall is off, and other router services such as upnp are all off.
I've also tried swapping out the edgerouter and just using the EA4500 functioning as a router and access point (I tried with upnp both on and off). I can still reproduce the same problem with 'Wireless-G' being the only way I can connect.
A friend came over with his Lenovo G500. He experienced the exact same problem. Back at his place we both experience the same problem on his Comcast supplied router/access point (manufacturer/model unknown). He too needed to explicitly set his router to 802.11g mode in order for both of us to connect.
I manually uninstalled the Microsoft driver and installed the driver in the support page for the S415. I can confirm this driver is the following:
For what it's worth, I have a wide variety of wireless devices in the house (ipod, ipad, nexus tablets, samsung note 2/3 phones, samsung ativ tablet, surface 2 pro, various usb wifi adapters, wii, and xbox) whose chipsets vary from Broadcom, Intel, Marvel, and Realtek. None of them have connection problems except for the Broadcom in the S415. With so many devices that use/need the extra bandwidth provided by 802.11n, I shouldn't have to reduce my access point to 802.11g.
Any other suggestions?

Hello. Well, I manually installed the correct driver, and also disabled the UPNP function on the router (Netgear router) to no avail.
It's quite random . . . it can happen several times within a 5 minute period, then may not happen again for a few hours. It's irritating as crap, gotta say. And, as with others, I have a number of other wifi enabled devices connecting to that router and do not have this problem with ANY of them.
If anyone has any other suggestions, please let me know. Really regretting buying this laptop at this moment.

After a few hour delay the laptop started dropping the internet again. I am disconcerted by the lack of a resolution to this issue, as i am contemplating taking Best Buy up on thier 14 day no question return policy. I did see the same unit at TigerDirect, with wiondows 8.1 installed and around $100 more. When i asked the tech what the difference was he said their model "newer"..... a revision perhaps? Anyway, it saddens me that with such models as the G575, and the Y560 under my roof that i once again have failed in finding a name brand I can trust to do the right thing no matter way the cost.

I just got off the phone with Lenovo support. What worked was manually installing an older driver:
Broadcom 4321AG 802.11a/b/g/draft-n Wi-Fi Adapter
Driver Provider: Microsoft
Driver Date: 3/14/2012
Driver Version: 184.108.40.206
I didn't know which of the "incompatible" drivers to choose from so it was good Lenovo support was able to confirm it was the 4321.

I spoke too soon. While I can now connect at 72Mbps, the actual throughput is abysmal (~10Mbps), and I lose packets. So this is still an issue. I hope someone in support is still watching this thread.
@lellis1959 - I'll assume you can navigate your way through this:
Device Manger : Network Adapters : Broadcom ... Wi-Fi Adapter : Properties (via right click) : Update Driver : Browse my computer for driver software : Let me pick from a list ... : uncheck 'Show compatible hardware' : (on the left) scroll down to Broadcom : (on the right) choose 'Broadcom 4321AG 802.11a/b/g/draft-n Wi-Fi Adapter
Hopefully you have better luck, lellis.

I've found a partial solution that allows me to keep my access point in mixed mode (so my other clients can connect at 802.11n speeds) while enabling the S415 to connect at 802.11g speed.
I installed the latest driver in the driver support page (version: 220.127.116.11). In the Advanced tab of the Broadcom 802.11n Network Adapter Properties, I set WMM to 'Disabled'. I've been streaming Olympics coverage via my HDHomerun Prime tuner for the past hour, and not a single hiccup.
It's not the 72Mbps I should be getting (since WMM is disabled) but at least it's a connection.
