    Broadcom 4352 AC card, low wireless signal.


    Yooooo! I have a Lenovo Y510p with modified BIOS so I could replace the crappy Intel wireless card that came with it (Intel Centrino N2230) for an Azurewave - Broadcom 4352. The experience has been good so far, the only problem I'm having is the low wireless signal with the card. I have other laptops that have higher range and strengths on the same place with older cards.

    I've tried verifying (and even swapping) the cables and noted no difference. I asked on another forum and they told me that it could be that the card is not receiving enough power, but I have yet to find a settings in the BIOS or in Windows that dwindles its performance. I have recently updated the driver from Lenovo's website and it didn't improve a bit.

    Any suggestions to improve the wireless signal? Thanks.

    Don't have a answer for this one but do you know if the Broadcom is better than the Intel 7260AC?

    I wonder how does it compare for connection quality though for WiFi... Wonder if Qualcom/Atheros makes one or not? Intel is good for wired NICs but sucks for Wireless.... From what I read, it's actually the Intel 7260 that supports WiDi as that's a Intel technology.

    Broadcom normally has less signal power than Intel and Qualcomm. Don't worry about signal strength since it doesn't translate to real world throughput (e.g. a 3-2 bar Broadcom chip can provide faster throughput than 4-5 bar Intel). I use Marvell 802.11ac rather than the Broadcom/Qualcomm/Intel chip though. As long as throughput is excellent, you don't need to tweak any settings and/or update drivers.

    @ Almighty

    Mini-PCIe interface is getting obsolete so you won't find any good replacement other than Broadcom BCM4352. However, there's another half-size mini-pcie form from Realtek called Realtek RTL8812AE: Realtek RTL8812AE miniCard - WikiDevi

    Realtek is well established in the integrated sound department, but I don't know their performance in the wireless department.

    On a side note, I really wanted Marvell to provide a dedicated half-size mini-pcie or an NGFF or M.2 since their 802.11ac chip in the Surface is performing really well while giving me NO problems whatsoever (no ping spikes, no low signal strength, etc.)

    Didn't know about this. What is it going to supersede it?

    NGFF or M.2 socket which ironically still uses the PCIE interface. The difference is that M.2 based chips are smaller than their m-pcie parts.

    If you buy a expensive gaming laptops, there's a really good chance that they both include m-pcie with 2x m.2 slots. These days if you buying a slim laptop, it will not include a mini-pcie slot, but rather an M.2 slot (aka NGFF) for WiFi. Good thing is many manufacturers are releasing their latest iteration in this form. At the same time, they may not release anything new for mini-pcie sadly.

    Never knew that they were going to use M.2 or NGFF sockets for it!
