Wireless net on campus, easy connection?
ok, i guess that this is a rather obnoxious question, but i would like to know before i get my macbook...
my campus is (for the most part) wireless (yay!!) i just want to know if i have to do or get anything special to et online.
Are there any fees?
do i just look for a signal, get one and just go online?
is it really 'just that easy'?
thanks a bunch!!!
Hello...
It is really that easy! Weeeeeeeeeeee. No fees. You open up your notebook and most of the time it will automatically connect to the stongest available WiFi network. Also I must mention that there have been some problems reported with the macbooks and MBP dropping wireless connections. I have had no problem with my macbook, so far, joining an open network.
Oh and the Macbook is fricken awesome!

Windows "Easy Connect" does not reply with the password / "Easy Connect is not Available"
Hello,
I have posted a related question some time ago, which was eventually resolved. However, after some time a problem with Easy Connect (used for MSRA) came back:
Whenever I arrive at the point in setting up a MSRA session where Easy Connect is needed, I get the reply: "Easy Connect is not Available". Here is an example of the problem:
Start MSRA
--> as expected, a window with "invite someone to help you" and " Help some who has invited you" appears
Select "invite someone to help you"
--> as expected, a window with "Who do you want to get help from" appears
Select "Invite someone to help you"
--> as expected, a windows with "How do you want to invite your trusted helper?" appears
Select "Use Easy Connect"
--> as expected, the temporary "Create invitation window / checking network capabilities" window appears
Next, I would expect this windows to close a new window to provide me with the Easy Connect password. However, instead I get the window "Easy Connect is not available".
I cannot continue. (I have screenshots so can repost with them if that would clarity my question)
Any suggestion how to resolve would be appreciated.
(Please do not reply with the 3 suggestions from the FAQ (both computers must run windows 7 / Access to internet is limited / your router does not support Easy Connect - doesn't help)
More background information and things I have tried:
The "Easy Connect is not available" window offers the "Tell me more about how to fix this problem" which I have tried, but those suggestions do not help
If I use the other MSRA option: "Help someone who has invited you" (this would be my typical use case), followed by "help someone new" and than select "Use Easy Connect", I also get the "Easy Connect is not available"
window instead of the expected option to enter the Easy Connect password. I believe this is that same problem.
This happed with both the 32 as well as the 64 MSRA versions
I'm using Window 7 Ultimate, 64 bit with all the latest updates
This desktop PC is wired to the internet via an Edimax gigabit switch, a Dlink DIR-855 wireless router and a fiber modem in bridge mode
The W7 desktop has a single active network connection only
I'm using Windows Firewall and Windows Security Essentials
Disabling the firewall on the PC did not help
Network discovery is enabled in Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings (that’s UPnP – right?)
The Internet Connectivity Evaluation Tool does not seem to be available anymore from MSFT sites
Restarting "Peer Name Resolution Protocol" did not help
Restarting "Peer Networking Identity Manager Properties" did not help
Starting up with a "Clean Boot" (disabled all non-Microsoft services using MSConfig) did not help
I would also be interested to understand how I can check on the status of the "Easy Connect" service. Is this a service hosted somewhere, or??
Thanks!Dear Andy,
Thanks a lot for your reply. Let me answer your questions:
Q: Could you use the other methods: save this invitation as a file and use e-mail to send invitation?
A: yes, that way I can establish a MSRA connection
Q: Have you disable other network connections, including disable all virtual network card?
A: if I check with ‘Device Manager/Network Adapters’ (or Control Panel/Network and Internet/Network Connections) I see two network adapters (my Asus motherboard has two network connectors). Both are available, but only one is used. I have
disabled one. Unfortunately, this does not solve the problem. I will leave it disable for now.
Q: To find detailed information about this issue, please locate to event view and find the logs about remote assistance.
A: I have to admit that the Event Viewer is unfamiliar territory for me. So, I’m not sure where and what to look for. However, as suggested, I found "Event Viewer (local)/Applications and Services Logs/Microsoft/Windows/Remote assistance/Operational".
Each time, I attempt to use MSRA/Easy Connect, it seems two entries are added. As I cannot seem to upload files with this post, here are just the two entries:
“Diagnosis Repro Attempt resulted in a failure.”
“Remote Assistance troubleshooting has confirmed the problem: Remote Assistance Easy Connect isn't available.”
If you need more details, please suggest what to forward or check. I'm eager to find a solution!

How do I set up my air port extreme to do port forwarding? Running 10.7.4 I have a IP camera on my local wireless net work that I want to use from my iPhone 4s and other computers.
In most cable systems, the router you have will plug into your modem and just work automatically. A NAT (Network Address Translation) router takes your external IP and hands out LAN (Local Area Network) based IPs. All of the devices you are working with right now should handle the change automatically unless you've changed from the default automatic configuration.
The problem with your wireless end of this is that the iPhone is not yet 802.11n, only 802.11g. Because that router is not dual band, all of your wifi devices will be forced to slow down to 802.11g speeds. This won't matter much for each device that's connecting to the internet, as your bottleneck is still going to be there. Where you will see slowdowns is device to device connections, like transferring data between the devices. -
Multiple Data Source (for FAILOVER) in Easy Connect Naming method
Hi All,
I was wondering if there is a way to specify multiple addresses as part of data source property in the connection string when trying to connect to Oracle with Easy Connect Naming method? this is basically for failover scenario.
I know its straight forward, if i use Connect Descriptor. But not sure how to do it with EZConnect
For ex. this is what I want to achieve with EZConnect
sales.us.example.com=
(DESCRIPTION=
(ADDRESS_LIST=
(LOAD_BALANCE=off)
(FAILOVER=ON)
*(ADDRESS=(PROTOCOL=tcp)(HOST=sales1-server)(PORT=1521))*
*(ADDRESS=(PROTOCOL=tcp)(HOST=sales2-server)(PORT=1521)))*
(CONNECT_DATA=(SERVICE_NAME=sales.us.example.com)))
I appreciate your suggestions...
ThanksYou might get better answers in one of the DB forums from a generic fail-over perspective as EZconnect isn't specific to ODP.NET.
I don't know if there's a way to do it or not with EZConnect version of the connect string, but you can certainly provide the fully qualified connect string without using tnsnames.ora..
constring = "data source=(DESCRIPTION=(ADDRESS_LIST=(LOAD_BALANCE=off)(FAILOVER=ON)(ADDRESS=(PROTOCOL=tcp)(HOST=sales1-server)(PORT=1521))(ADDRESS=(PROTOCOL=tcp)(HOST=sales2-server)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=sales.us.example.com))); user id=scott;password=tiger"
Hope it helps,

Try to use easy connect to connect from isqlplus but to no avail
Using the Easy Connect Naming Method
from http://download.oracle.com/docs/cd/B19306_01/network.102/b14212/naming.htm#sthref783
I want to connect from isqlplus remotely.
pardon me if I ask this stupid question,
do I need to install oracle client to use isqlplus. if yes, then no need to answer the above question.
I mean with browser no doubt I can reach the url, but when it prompt for the connect string, i try to substitute the
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = globalro-417667)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = tomkyte)
so I wonder if I'm doing the right thing or not.
thanks!Hi,
See the link care fully, the page which you reffered it self says "This chapter describes how to configure connectivity information for client connections to the database server." So Client is required.
Clients can connect to a database server using easy connect naming if the following conditions are met:
- Oracle Database 10g Net Services software installed on the client.
- Oracle TCP/IP protocol support on both the client and database server
- No features requiring a more advanced connect descriptor are required
Every thing is there in ORACLE Document.

Question about "Easy Connect Naming"
Good evening,
My installation consists of 11gR2 where both host and client are on the same machine.
I wanted to test the "Easy Connect Naming" functionality, to that end, I renamed tnsnames.ora and proceeded to connect using the following command:
sqlplus sys/abc123@"Oracle2Day1.john.local/orcl.john.local:1521" as sysdbaas expected, the command was successful in connecting to the orcl instance.
To ensure that everything was as expected, I also tried:
sqlplus sys/abc123 as sysdbaUnexpectedly, this command also connected to the orcl instance.
I expected it to fail since there is no tnsnames.ora and I did not specify the host and service names.
The question is: why was the command sqlplus sys/abc123 as sysdba" successful given that there is no tnsnames.ora ?
Thank you for your help,
John.The question is: why was the command sqlplus sys/abc123 as sysdba" successful given that there is no tnsnames.ora ?Above only works when logged directly on to DB server, because this flavor of connection does not use SQL*Net; but uses BEQ protocol.

Upon waking from sleep, laptop will not reconnect to wireless net.
If my laptop is on and I'm using it and I close it to put it away for a bit, when I come back to open it, it doesn't reconnect to the internet all the time.
I have to restart the computer in order to get it to reconnect to my wireless net. Just wondering if anyone knows what's going on.
Thanks!besides setting the network as preffered and in the network settings udner the options for airport make sure it will connect to any available network, there isnt much else to do
some times it jus takes 30-60 seconds, also check that the network is paired to the location (if you have separate locations) -

Are you using a v6 uitlity.. because it is a toy.. ??
Get v5 utility and then you can hold down the option key and select the right mode.
If you have lion, just install it.. For ML follow this.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool. -

Why can't I connect to my brother MFC-J4510DW printer wirelessly? The printer is connected to the router.
I can surf the web. My wife can print from her PC wirelessly on it.
I wonder if some security setting may be keeping it from connecting to my MacBook Pro. I've installed the software, firmware and driver updates but
it still shows "off line"
with the printer power on. Any suggestions?All I can suggest right now is back up first the try to reset the printing system, (all printers in the list will be removed).
Then connect directly to the printer via ethernet or to the Mac using USB and restart the efforts you have made up until now.
As for router settings, it's possible but not likely that your router only allows a small number of clients. It's also posible that you have MAC address filtering on, lastly are you using the correct wireless protocol, (802.11a/b/g WEP or WPA etc)? -
Wireless net does not work after installing SP1 for Vista - Error code 10
After installing Vista SP1 on my computer (T61 - Vista Business 32 bit) my intel 82566mm wireless net does not work.
Windows says "Error code 10" and suggests that I update the driver. I have downloaded the newest driver via another computer, but it does not help. Still error code 10.
Any one else has the same problem?I fixed the problem. Uninstall iTunes and then reinstall it clean. Looks like upgrading is problematic.

My HP (USB connected) and Epson (wireless) printers keep losing their connection with my Mac mini. I have to physically disconnect the HP and then reconnect for the Mac to find it. Turning off the wireless Epson doesn't resolve anything. All software/drivers have been updated.

Can this be done? Airport extreme connected wireless in extend mode to connect a wireless Mac Pro with an ethernet cable from the extended airport extreme.
This will work.....IF....you also have an Apple AirPort router configured to provide your wireless network.
In other words, you need to have two Apple AirPort routers to extend a wireless network.
When the AirPort Extreme is configured to "extend" the wireless of the "main" AirPort, it will provide more wireless coverage and the Ethernet ports are enabled, so you could connect your Mac Pro to any of the Ethernet ports and use that as a network and Internet connection. -
ORA-12514 with Easy Connect only

)I put the listener in trace at the SUPPORT level. I can post that dump as well if it would help?
Without the Easy Connect connection identifier is it that I'm connecting via IPC? This is preventing me from remotely connecting via sqlplus or JDBC over an SSH tunnel of 1521 (the box is firewalled).
Thanks!

Edited by: ibrandt on Sep 8, 2008 3:19 PM - Formatting.Well, I've gotten it to work by changing 'localhost' to 'myhost.mydomain.local' (name changed to protect the innocent) in tnsnames.ora and listener.ora, adding myhost.mydomain.local to my local DNS server such that it resolves to eth0's external IP, and restarting oracle. After that...

The command completed successfully...which is notably different from before. After that I can connect with:
sqlplus system/password@localhost/XEAlso of note, using the external IP directly in tnsnames.ora and listener.ora did not work.
So my new question is, why does Oracle need a HOST=hostname--where hostname resolves to an external IP--to startup correctly? Though I have 1521 firewalled from the outside world it seems like an unnecessary security hole. -
Unable to use "easy connect" method to XE database
All,
I have an XE database running on Oracle Enterprise Linux. If I create a tnsnames.ora entry I can connect to the server fine. However, if I try to connect via the easy connect method
sqlplus user@host:port:sid it fails with
Enter password:
ERROR:
ORA-12545: Connect failed because target host or object does not exist
the hostname I am using is definitely correct and I've also tried with ip address and get same error message. If I change from SID to SERVICE_NAME
sqlplus user@host:port/service
I get the following error message
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
I've used both XE and xe as service name. The service name in my tnsnames.ora entry that works uses lower case xe for service name.
Any help out there would be appreciated.Maybe this is more significant for you ?
