The Blackberry 8520 has all the virtues of a well designed and aesthetically satisfying widget, but many times it displays a telephony problem. Many Blackberry 8520 users are facing a problem when connecting to Wi-Fi, because it uses advanced hardware models. One could get rid of it easily with the help of telephony. Internet telephony is software which crafts the use of Internet protocol for transferring the say-so signals in digital set-up in isolated packets that allows three or more phones to connect themselves. With the aid of this software, users could be able to converse over the net via microphones as well as listening through headphones.
Blackberry 8520, I actually have a UTStarcom adsl 2+ router(modem) which basically has a wifi network which can be connected to a wireless network. When I am searching on my Blackberry the UTStarcom is coming as open. When I am trying to connect it's showing the message 'cannot get IP'. I tried a different thing on my Blackberry. I opted for manual connection instead of automatic. Then in my system which basically runs on windows xp service pack 3, I made a profile with wireless network that ssid thing and inserted a wep key for about 5 characters. I even tried this, on Blackberry it was sometimes coming as not able to connect or cannot retrieve IP. Can you give a solution for this.
Try WPA-PSK [TKIP] + WPA2-PSK [AES], which is a higher level of encryption and the Blackberry connects right away. The software on the Blackberry is more advanced than the older models, so it's using a higher level of security. Thanks to Ryan, my problem is solved and it only took 15 minutes! For those of you that don't know the difference in the wireless security settings that I mentioned above, here are the basics: TKIP (Temporal Key Integrity Protocol) and AES (Advanced Encryption Standard) is a choice between old and new technologies. Both WPA-PSK [TKIP] and WPA2-PSK [AES] offer good security, but WPA is theoretically breakable and WPA2 with a strong password can withstand an attack for years. WEP (Wired Equivalent Privacy) is the oldest (1999) Wi-Fi protection standard and can be cracked in a matter of minutes these days.
