Wireless Network Card (Barely Working?)

Specs: Microsoft Windows Vista Ultimate, 3.1 GHz / 4094 MB
Ok I have my desktop which is wired to the router sharing wire verizon wireless card for internet access across the network. Up until about a week ago this all worked well. I have a laptop connecting wirelessly. Recently the network card has been doing an odd thing. once the computer falls asleep, hibernates, restarts the card can't find my network. I have to delete it in device manager and then let it reinstall itself. Since then network transfer (including using the internet) is VERY SLOW, but still works at the slowest rate you could possibly imagine. usually no more than 1 KB/sec. I first disabled all firewalls on the host computer as well as the laptop and firewall and security on the router. No improvements. internet on my PS3 is slow but network streaming is good. My moms netbook connects and runs fine. Also the wired connection on the laptop works fine. All of these also work fine with firewalls running. The laptop shows a 54Mb/s connection to the network and pinging works equal to the desktop both on local network pinging (1ms or less) and internet address pinging (anywhere from 300ms to 2000ms). Once again though i ran the ping both simultaneously and by itself with my desktop. All results are about the same. It took 4 hours to transfer a 800MB file across the network. Is it possible that the card is somehow damaged that would allow it to still work slightly or is there possibly SOMETHING in the software causing this? Oh and all computers were running different versions of Windows 7(Laptop-HomeP, Desktop-Ultimate, Netbook-Starter. Thank you for your time.

You do understand wireless has a bunch of overhead wired does not?

300ms to 2000ms is pretty HIGH for pinging internet ips like yahoo.com This indicates poor internet bandwidth. Especially when compared to the local ping times.

1ms or less for local means there are no issues with your wireless card as those are great stats.

If the 800meg file was over the local network the biggest factor will be reading and writing to the hard drives.

Throughput is limited by the weakest [slowest] link in the chain

As far as the laptop and desktop; I use them both for all kinds of office apps, AutoCAD, Games, Viewing and editing pictures, watching movies... well just about everything and neither have any lag on any of these tasks so I would assume the hard drives, cpu and so on are in good working order. Yes the file was over my local network. Also attempts were made to do the same network activity while in the room 5 feet from the router with no improvement. Also the manual switch on the laptop for the card is in the on position (tried both ways just in case).

Everything works fine on other wireless devices so probably not the router though I do have another I can try just in case.

I use Verizon Broadband card for internet cause i am not in access area for Cable/DSL. Naturally the closest cell tower is well away also. I have to use an antenna ran from outside and still only getting a max of -85dBm but usually around -90dBm. My bandwidth does suck, but i still get a decent 25 - 100 KB/s considering. Miracuosly got up to 250 one day. Thanks in advance.

There does not appear to be anything wrong with either the wireless card, router or your file transfer.

You may want to consider doing the same file same unit but wired and see what time it takes for comparison.

Transfer:
Wireless(from before) - 4 hours (app .05MB/s)
Wired(Today) - 5 Minutes (Averaged about 3MB/s)

Wireless(Newegg.com) - 2 minutes approximately
Wired(Newegg.com) - 8 seconds
I deleted temp internet files between loads to avoid corruption of test.
