iOS 6.0.2 was specific to the iPhone 5 only, no other device gets it. The latest iOS for iPad is iOS 6.0.1
If you provide some details of your wifi issue (make and model of wifi router, specific errors you may experience, does your wifi work on other networks, do other device work properly on the network with the issue, ...) someone will likely be able to help.
iOS 6.0.2 does not apply to the iPad 4.
If you are having WiFi problems it is necessary to isolate whether the problem is with your network or your iPad. Note: Do NOT consider your network to be blameless if some other devices can connect to it.
First, test your iPad 4 on some other networks: a friends, Starbucks, Barnes & Noble, etc.
If it works well there then the problem is with your network. Try restarting your router by removing power for 30 seconds. If that does not help check for a firmware update for your router. If none exists which corrects the problem consider replacing the router.
If your iPad does not function well on other networks it possibly has a hardware problem. Contact Apple or visit an Apple store for evaluation. They can provide a replacement if your iPad is bad.
If you need more help please give the make, model, and version of your WiFi router and how you have it configured.
On the iPad, try
Settings -> General -> Reset -> Reset network Settings.
Then reconnect and see if that helps.
If the other devices are all fine with the netgear, I doubt the problem is the router itself, but it could be a fubar'd network setting on the iPad. A network settings reset, or a simple iPad reset might fix that.
I use a Netgear N900 (wndr4500) and my iPad 4 and iPhone 5 connect fine on either 2.4Ghz or 5Ghz, and I've not heard of any specific issues with netgear routers and iOS devices.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
• Launch Settings app
• Tap on Wi-Fi
• Tap on the blue arrow of the Wi-Fi network that you connect to from the list
• In the window that opens, tap on the Renew Lease button

Unable to Connect After iOS Update - saw this solution on another post.
Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
If any of the above solutions work, please post back what solved your problem. It will help others with the same problem.
this is indeed a bug. I did watch a youtube video showing that the iPad is not compatible will all type of routers. The guy in the videos says the WiFi only works after change to Netgear router. The reset stuffs don't work. I'm using Asus DSL-N10E and have the same problem. Is there any temporary solution for this until the IOS 6.1 release ? Some mentioned about "downgrading the framework" ; not sure what is it. Can anyone advice on this ?
Same issue. I can connect to my home wifi from my macbook, pc and iphone(ios 6.0.1) from all rooms but my new ipad (with os 6.0.1) works only in my living room where my router is. I get a weak signal at times in my bedroom and loses connection frequently. I tried all the options to resolve this but havent been able to fix this yet.
I cant change my router when all my devices work properly when only my ipad cant connect to the wifi.
Also, i dont know if there is compatibility issue between ios 6.0.1 and my router since my phone with the exact same ios update works perfectly fine.
I now seriously feel like returning my ipad because I cant seem to get a fix for this issue.
I have an ipad 4 and it is also experiencing drops when I'm not within 10 - 15 feet of my router. The ipad still has full wifi signal according to the display, but websites, iTunes and anything that requires the Internet won't function. I've renewed/ released, powered off, hard reset, back up and set up as new, nothing seems to fix this issue. I've sent mine into Apple, but so far it's passing their tests. I don't see why I need to buy a new router or make changes when my iphone, MacBook and other wifi devices work with no problems. This is something either software or hardware related. I just wish they would acknowledge that people are having problems. When I asked an Apple employee if this is a known issue, they said "it's the first time I've heard about it." If its an issue, own up to it and fix it. I have enormous respect for honesty. I hate being given the run around and being told that its my network that's the issue.
Apple hasn't contacted me back yet, but I received an email from them last night saying that they are replacing my iPad. Apparently it must have failed some type of test and I'm kinda curious as to what they experienced. I hope their refurbs are as nice as people claim them to be cause I've only had my new one for 3 weeks and now it's getting replaced by a refurb. Refurb is an ugly word, but I assume the wifi will function better. If not, I guess I'll be calling Apple back.
Curious ashaw, are you going to wait out for a software fix? I believe you have a year for hardware problems with AppleCare.
