The Intel is still reliable for me, but it's more prone to WiFi interference and has more latency than Broadcom and Qualcomm Killer chips on average. I actually wanted that Broadcom card too but I don't want to throw away the $25 dollars I spent on my Intel Dual Band Wireless-N 7260. Here's where you can buy it: Azurewave AW-CE123H 802.11ac/nbg WiFi+BT PCI Express Moduleīroadcom BCM4352 / Bluetooth 4.0+3.0 HS Class IIĪzurewave is just a rebranded Broadcom WiFi card for retail purposes. If you want the card that has the same features as the Intel Dual Band Wireless-AC 7260 without the driver issues, I suggest this Broadcom card: There is a problem when I am connected to my router and Internet. I've had laptops with Broadcom 802.11g chips on them and so far they have performed excellent with no ping spikes. I am owner of Dell Studio 1555 and I have Dell Wireless 1397 WLAN Mini Card on my board. Notation: Fixes: Customer experiences slow connection speed and slow domain logon when wired LAN connection not present. Even my Intel Dual Band Wireless-N 7260 sometimes have ping spikes that results to lag while playing online games. So to cut a long story short- the card is crap and in your setup as it is, it's working at it max speed - nothing you can do other than forcing 40MHz channels which would make it run at roughly 150mbps and your other devices at roughly 300mbps.Ĭlick to expand.I can't recommend Intel cards right now as they have driver issues that results to sporadic slow throughput. You could get higher speeds from all devices by setting 40MHz channels on router but that might not be possible since according to 802.11n specs routers should revert to 20MHz channels when there are neighboring networks running (and I'm pretty sure that are other 2.4GHz networks where you are). Max speed Atheros would be able to achieve in your setup would be 72 mbps with 400ns guard interval - with the same guard interval your other devices should be able to achieve 144mbps but seeing as Atheros manages this speed only for brief moments I assume other devices would only jump to 144mbps for a moment too(if even that). Since Atheros AR5B225 is based on a AR9004WB wireless chip which can only use 1 spatial stream it would be possible for this card to achieve speeds that are adequate at 20MHz channel with 1 spatial stream and 64-QAM modulation- which would be 65mbps.

It does not feature any special highlights. It's a bit complicated but overall it's correct.ġ30mbps is achievable only with 20MHz channel width and 2 spatial streams and 64-QAM modulation (and one of two coding rates). The Wi-Fi card dubbed 'Dell Wireless 1705' is actually a wireless adapter from Qualcomm/Atheros.
