Full coverage: Apple's iPad

Computerworld - Some owners of Apple's new iPad have complained of weak wireless signals, dropped connections and slow surfing speeds, messages on the company's support forum show.

Although users have also reported problems with recharging their iPads from Windows-based PCs or synchronizing the tablet with other computers, Wi-Fi issues have garnered the most complaints, as tallied by the message counts on multiple support forum threads.

As of late Monday, the thread titled "Weak wifi" leads all others with more than 130 messages, and nearly 13,000 views.

"Signal is weak, downloading anything is painfully slow and it will drop the signal and go offline every 5-10 minutes," said a user identified as "mbell75" early Sunday, near the beginning of the thread. "Pretty annoying."

"It will work fine for a while, but show a low signal. Then, after a few minutes of use, my connection will drop completely and I will have to reset my wi-fi radio," complained "mlp8104" in a message Monday afternoon.

The biggest beef was that the iPad's Wi-Fi signal indicator would fluctuate, going from full-strength to the lowest level without warning, or any change in the tablet's location.

"My wifi went down to 1 bar after working great for a few hours," said "syunker" Monday. "My download speeds started to crawl, I couldn't even surf the web. I rebooted my router and it didn't help."

Several users said their iPads could not acquire a signal, or only a faint signal, while other devices, including new Apple laptops and iPhones, had no similar trouble. "In our living room where laptops get a full signal, my iPad gets a very poor signal which is so bad that it even cuts completely out sometimes," complained "Panjandrum" Monday morning. "I had to walk the iPad into the same room as my router to get a movie rental to download."

As is often the case on Apple's support threads, users hoped that a software update to the iPad's operating system would not only solve their problems, but be released soon.

Others, however, chimed in to say that they were perfectly happy with their iPads' Wi-Fi signal, which was strong and stable at home, work and in public hotspots at locations such as Starbucks.

Some who reported that their iPads intermittently lost a Wi-Fi connection said that they solved the problem temporarily by shutting down the iPad, then restarting it. "But should I have to do that with a device that costs this much and has so much hype about changing the way we use the Net?" asked "sandersn" on Sunday in a different thread.

Monday, Apple posted several iPad-specific support documents to its Web site, including one that suggested users modify settings on their wireless routers. Another troubleshooting document told users to "Move closer to the Wi-Fi router or hotspot," if they were having problems.
