I have an iPad Wi-Fi, not the 3G model. Cool device but worst Wi-Fi out of like 12 Wi-Fi enabled devices in the house. Running a Linksys 802.11n Router which enables Wi-Fi on my iPhone way out in my yard. The iPad has trouble operating 3 rooms away from the Router in the house! It shows high signal strength but the IPad has to be turned particular ways to get transfers to occur. Anyway, I just downloaded the new OS that says something about improving Wi-Fi connectivity. I don't see a difference really.

Does anyone else have Wi-Fi issues?

Is there any fix?

FYI on August 18
Here is what resolved my issues:

BEFORE
Linksys WRT300NV1 Router using WEP ( a few years old for sure)

AFTER
Netgear WNDR3300 dual-band Router using WPA2

I had tried moving the Linksys around (antenna direction, etc.), it helped but still wasn't snappy response and sometimes just died. After I finally got the Netgear router talking with my Comcast modem, it worked normal and I'm satisfied now.

Mine seems to be okay in the next room, it looks like it picks up outside, but it doesn't work.

No WiFi problems anywhere in the house. Haven't tried outdoors.

No Problems Here

Seems to work fine for me ... In different cities and three different airports. At home I have an airport extreme router.

Mine's OK in the house and out on the porch.

I totally agree with pcor. Reception compared to a laptop of mine is much worse
I can see several neighborhood wifi's with the laptop but not with the iPad.

I don't have a home WiFi router but my neighbor has one unsecured and I can't help but connecting to her signal by default.

Yep, mine is much worse than a first gen iPod touch. I hope today's fix does the trick.

The newest 3.2.1 release by Apple fixed my wifi problem.

Found a bit more info

Apparently a few internet sites have referenced this issue. Also, I found on ifixit.com that the antenna is right behind the Apple logo on the back.

Here is what I did to fix my issue.... Turned the iPad upside down.

iPad right side up ( home button at bottom ) most sites take 30 seconds to come up if ever.

IPad upside down ( home button at top) sites come up rather snappy. Cool, but weird.

There must be some issue with polarization w the iPad antenna relative to the Wi-Fi Router antenna. Regardless it's pretty screwy to worry about how your iPad is rotated. Anyway, I experimented with multiple sites to make sure it wasn't server dependent. It isn't.

I' m going to try to reposition my router antenna tomorrow and see if that improves the situation any.

In the meantime, I'll be down side up!

I'm using a TrendNet G router and works great for me with all devices. Almost daily me, my dog and iPad walk over to our favorite resting spot in the park across the street. This is roughly 300 feet from my upstairs router. My iPad works great every time. I've downloaded magazines and games without a hitch.

I had WIFI problems to and I found out one of my Apps was causing the problem.
The App causing the problem was "The Weather Channel"
Every time I installed the App my WIFI connection would get weak and then I was prompt with "Your not connected to the internet"? Once i uninstalled the app I had a strong signal and I wouldn't have and connections problems.
I reloaded the App and sure enough I had connections problems again.
My suggestion is to uninstall some of your apps one at a time and see if you wifi connection improves.. GOODLUCK

If update doesn't fix it, bring it to apple store for an exchange. You might have a dud :/

Update fixed mine too. Solid now

This seems to be a really quirky app. For several days when I would tap the icon, the splash screen would come on, but after a minute or so, it would just go back to the main screen. The all of a sudden, for no good reason, it just started working again. I guess I could ask for my money back. Oh yeah, it was free!

EDIT: And back on topic, the update really helped my connection. I didn't think I had a WiFi problem before, but now I can use "N" at much faster speeds.

I have strong wifi connections. I'm on the new uverse motorola unit. I can access my wifi from the back yard, garage, and everywhere in the house.

Updated mine and still only get one bar in a room about 50 feet from router. But get at least 3 bars om iPhone in same spot.
