But there is a clue in there which is -> "as these problems are only experienced when I'm using this router. "
That's fantastic since a router is cheaper than any service call for router or laptop.
As to the sleep issue, try hibernate next and my bet is that Sony and most techs will have you restore the machine to factory condition and if it still hangs then it's time to get it repaired.
Let me preface this by saying I'm not the most tech-savy individual out there, but I'm more capable than most people. I've spent collectively dozens of hours in the past year trying to find a similar problem online to this on forums online and have come up short after trying several things. I think there's some sort of data log I can access through through the command prompt that might help people ascertain the problem, please let me know if that would help.
I'm running windows 7 on a custom (and pricey(you'd think this wouldn't be a problem)) sony vaio laptop, purchased about a year ago if that helps.
So here are the problems: Everytime I shut my laptop to enter sleep mode it freezes, then within a few minutes will shut itself down, (the kind of shutdown that makes me have to reboot through that crash screen thing, you know what I mean); I frequently have my wireless internet connection switch to a limited access state where I can't do anything online; when this happens, messing with my network stuff (running a diagnostics check, opening properties, disconnecting/reconnecting attempts) will result in "microsoft explorer" crashing - after it "restores" itself, clicking on the wireless thing in the bottom right of my screen (if its even there) will give me no results, and I need to reboot my computer to have any wireless abilities again.
Now heres a big peice of the puzzle, I only experience these problems at home, where I think the wireless router is one of those newer n-type ones (I don't know what that means.) When I'm at school or at a friends house I experience none of these problems and the computer runs seamlessly. Nobody else in the household experiences these problems on their laptop, desktop, tablet or whatever; only this computer has that problem. I've had the problem ever since I bought the computer. I should also note that several times I've tried re-installing the wireless driver, always to no avail.
I suspect theres something about the wireless network that doesn't allow my computer to sleep when I shut it down, and thats why it freezes, I also suspect its related to why windows explorer crashes whenever I mess with the wireless settings too much, as these problems are only experienced when I'm using this router.
I'm hoping the problem isn't that my wireless card is so outdated it can't deal with these new problems, because dishing out 1600 for this computer last summer made me assume I wouldn't have to deal with stupid issues like this.
For the past year I've just been dealing with this without asking for help on a forum and now I can't take it anymore. I don't want to pay Sony 500 dollars to fix a problem that it had out of the box. Please let me know what additional information might be required to ascertain the problem, and how I can provide that information. Solving this problem will alleviate an unbelievable amount of frustration which I experience daily, please help!
