USB 2.0 vs PCIe 1.1 bus speeds?

I am in the process of updating my network and I bought a Linksys AC 900 EA6200 router with speeds up to ~840 mbps.

Until I can upgrade my PC's They have USB 2.0 ports, I was going to install a PCI express x 1 USB 3.0 card to get more speed but I just found out they are v1.1 slots and if I understand correctly they only get 250 mbps speeds so I am better off using the USB 2.0 ports, is that correct?

From what I was told a wireless USB adapter might get half of the advertised speed so would it be to my benefit to get a USB 3.0 with max speed of ~840 mbps even though I know it won't get those speeds it seems like a better option than a USB 2.0 adapter that advertises 450 mbps.

Is there anything I am missing that would allow me to get faster network speeds?

I have an Intel N 6205 wireless card connected on a PCI bus in a fairly new 64-bit laptop. The maximum speed copying a very large file over my network is about 90 mbits/second.

The network is a Cisco RV042G with 800 mbits/second throughput. The wireless is a Cisco RV220W wireless router.  

So if you are using a USB connection to give you wireless, 250 mbits/second seems quite high. Remember that wireless speeds are rarely up to the top limit specified.

Is it really impractical to use wired Ethernet in your situation?  It would be much more reliable and predictable.

I have seen too many clients use wireless because "it was too much trouble to run cable".  While that can be the case, it is often much less of a burden than troubleshooting wireless problems in the future.

Of course, if you are looking for portability with a laptop, the disadvantages of wireless can make up for the disadvantages.  I try hard to avoid wireless when dealing with stationary computers.

"...  I was going to install a PCI express x 1 USB 3.0 card to get more speed but I just found out they are v1.1 slots and if I understand correctly they only get 250 mbps speeds so I am better off using the USB 2.0 ports, is that correct? " ==>  NO !!   Not at all.    With a single PCIe v1.1 lane you'll get 250MB/s of bandwidth, which is FAR more than any USB 2 or wireless adapter can come close to.

I think you're confusing Bytes/second with Bits/second in comparing the various devices.

As for whether or not there is  "... anything I am missing that would allow me to get faster network speeds?"  ==>  It depends on whether you mean networking, or wireless networking.    By far the BEST thing you can do to increase your networking speed is to run Cat-6 cable to all your devices and use Gb adapters with a Gb router and switches.    But if you're referring to your wireless infrastructure, your already pressing the limit on what you're going to achieve -- about the only other improvement you can make is to replace all of the adapters with dual-band Wireless AC adapters that can maximize the speed when connected with your new router.

But no adapter will overcome the most basic rule of networking:  Wired is ALWAYS better than wireless :-)

Ahhhhhh, I am glad you brought that up. I was looking online comparing and I had a brain fart and saw MB/s and mentally compared it to mbps. I thought that was really odd, I thought for sure the PCIe would be much faster than a USB port, now I know why.

I am dealing with two PC's now and one I will keep wired, I need to install a gig NIC in one of the PCIe slots and the other PC I will have to have wireless so for that one I will look at a PCIe wireless card instead of a USB adapter.

So if I have a gig Ethernet/AC~840mbps and use a gig NIC in a PCIe on one and a wireless PCIe card rated for as high a mbps rating as I can afford (at least ~840) what kind of LAN speeds could I expect? 1/2, 3/4 top speed?

I've not used any AC wireless adapters, but with Wireless-N if you get 50-60% of the rated speed you're doing well; so I'd expect the same with Wireless-AC.

With wired Gb you can get very close to the rated speed => I routinely get 120MB/s transfers (960Mb) ... which is about 95% of the theoretical max.    That's with all Gb infrastructure and wired Cat-6 throughout my home.
