That may change based on what your neighbors are doing on WiFi, if they set up or remove any WiFi networks, or if their routers are set to Auto and moving around as well. That's especially helpful on the 2.4 GHz band because there are only 3 non-overlapping channels in total anyway, and if your router is on Auto it can figure out which one is clearest at any given time. Anyhow, only connecting to one band is expected.Īs for your WiFi settings, I would set your channel to Auto on both bands if your router allows it.
Some early dual band routers made users choose which band they wanted to use because they could only support one at any given time, which made them pretty impractical as primary routers because some low-end devices still only support 2.4 GHz because they simply don't need the extra throughput of 5 GHz and benefit more from the longer range of 2.4 GHz. Dual bands simply means they support both bands, and "simultaneous dual band" on routers means they can broadcast on both bands simultaneously. If you managed 867 Mbps of actual throughput with that router and WiFi card, I personally would be quite happy with that result.Īs for dual band, WiFi clients do not connect on both bands simultaneously.
But also be aware that performance for WiFi speeds, as with pretty much every other standard, are quoted as a theoretical max, which means you are unlikely to ever see that level of performance in the real world. If you have something like a NAS device on your network that's connected via wired Ethernet, you could try transferring large files back and forth to see what your performance is like. It's also not an especially reliable indicator of actual throughput.
But make sure it's M.2 rather than you'll find that the speed reported in Windows will fluctuate pretty frequently. You might have to do the same, but since I don't follow Dell Wireless cards, I don't have a specific recommendation to make for you on that front. I finally gave up and considered that perhaps Intel WiFi wouldn't work on an NVIDIA chipset, so I bought an Dell Wireless card that used a Broadcom chipset instead.
They either weren't detected at a hardware level or Windows couldn't start the device properly even after I tried installing the drivers multiple ways (I'm an IT pro). Long ago my wife had a Dell Studio 14z that used an Intel processor but an NVIDIA motherboard chipset, and I tried 3 different Intel WiFi card models, none of which ever worked. In that case, Intel WiFi cards may not work.
Additionally, I forgot that having a "5" as the last digit in your model number means your system uses an AMD processor and therefore a non-Intel chipset. "UPDATE: According to the Inspiron 5755 Specifications document here, you have an M.2 slot for WiFi, not an mPCIe slot.
I read that even if i got M2 slot that no driver will work for AMD based laptop is that true you where mentioning that it could cause issue.
