I have Inspiron 15 5577 laptop which came with Intel Dual Band Wireless-AC 3165, which is totally **bleep**!
So i wanted to upgrade it to Intel Wireless-AC 9560.
Is it compatible?
*Also does upgrading it voids warranty?
Yes it's possible, in fact the manual for your system that you can find on support.dell.com even gives you a step-by-step guide complete with diagrams. Dell systems do not have a WiFi card "whitelist". I've upgraded lots of Dell laptop models over the years and have never had a problem. In terms of the warranty, obviously the new card won't be covered by the warranty, and if you break anything while performing the swap, that damage wouldn't be covered either, but other than those restrictions, your warranty will remain intact.
The specs for that system indicate that it uses an M.2/NGFF slot for WiFi, which means your best bet for Intel Wireless is either the Intel 8265 or the Intel 9260. The latter is newer technically better, although you may not notice any difference in the real world, especially if you don't have a high-end 802.11ac Wave 2 router and/or only use WiFi for Web browsing rather than a lot of high-bandwidth traffic on your LAN. However, the 9260 is still quite new and is therefore difficult to find from reputable vendors, and it's not clear where/how the random third-party sellers on Amazon and eBay are obtaining their inventory, which is why I also suggested the much more widely available 8265. You definitely do NOT want to get the Intel 9560, however, since that is a version of the 9260 that depends on the CPU to have certain RF components, which yours wouldn't.
OK. So can you please give me some links to sites which i can purchase genuine Wireless-AC 9260?
No, because if I knew of a reliable place to get one, I would have just recommended buying the 9260 from a vendor like that instead of warning about the hazards of buying that card right now.
Oh, but can i ask you why?
So sellers on AliExpress are selling fake ones or something? (Also they have 1000+ positive reviews)
Why is that card hard to get?
It's hard to get because it was just recently launched, and some vendors were selling them before any PC OEMs were even using them in their systems, which I find suspicious. I don't know anything about AliExpress one way or the other, but positive reviews do not mean they're sourcing their components legitimately. Here's what I posted in another thread here recently about someone who was having issues with his 9260 that it turned out he purchased through a random source:
Did you get your 9260 from a reputable source? Some people started selling them on eBay and on Amazon as third-party sellers even before any OEMs were using them, so it's not clear how those sellers got their inventory. If you know anything about manufacturing practices in China, your seller could have gotten units that fit any of these descriptions:
- "Scrappers", which are units that failed some part of the QA check but that the manufacturer (i.e. the Chinese factory, not Intel) decided to sell themselves.
- "Midnight runs", which are units built during unauthorized production runs at the factory so that the manufacturer can sell them at a larger profit by cutting out the company that actually placed the order (Intel). These are sometimes identical to the true production run units, but sometimes the manufacturer substitutes cheaper components to make an even larger profit on these.
- Full-on counterfeit units that may have come from a manufacturer that isn't even supposed to be making that product.
@boed and @tns19 the Intel AX200 is indeed the new top WiFi card, although whether it will make an actual difference in your usage would depend first on whether you even had 802.11ax wireless router/access point equipment and then whether you actually do things over WiFi that would benefit from the extra performance. Looking over the AX200's Product Brief PDF here, I don't see any mention that it requires CNVio, so in theory it SHOULD work in any system that has an M.2/NGFF slot for WiFi -- unlike the 9560 which is basically a 9260 that relies on CNVio and notes that in its own Product Brief PDF here. But I can't be sure, since I've never retrofitted an AX200 to an older system. So I would say that if you want to get the latest and greatest but aren't sure whether it will work, buy the AX200 from a retailer that has a convenient return policy. If it works, great. If not, then return it and get the 9260 instead.
