When it works:
Wi-Fi (wireless, high-speed Internet) is without a doubt the
best way to connect to the Internet. It’s fast, it’s always
on and it’s pay-as-you-go – no long term commitment.
You can use it wherever there is a hot-spot and the number of them
is growing all the time. Many of them are free. And, obviously,
you don’t have to mess with any wires! Getting online is
SO easy!! Just turn on your computer, give your adapter a minute
to detect the hotspot and start browsing the Web!
When it doesn’t work:
If a Wi-Fi connection isn’t working, troubleshooting the
problem can be very difficult. There are 3 primary factors in a
Wi-Fi connection all of which need to be functioning together to
make Internet access happen.
- The source of the Broadband Internet connection. Usually
DSL or Cable, but possibly a T1, a ‘point-to-point’ connection
to a local ISP or a Satellite connection.
- The Wi-Fi distribution equipment. A Wireless Access Point,
possibly a gateway and one or more antennas and amplifiers.
- The end users’ Wi-Fi adapter and computer.
In an RV park, it looks something like
this:
The basic troubleshooting process goes like this:
- Is the user’s Wi-Fi adapter on and functioning? There
are usually lights on the adapter, laptop case, or onscreen
icons to let you know this.
This is a special problem for internal/built-in adapters. They
usually have some way to turn them on, but it is not at all obvious.
Every computer is different. Look for a button, or a function
key.
- Is the user’s Wi-Fi adapter sensing the availability
of the wireless network?
After about 30 seconds of being on, a little window should
pop up with a message like "Wireless Network is Available."
If that message does not appear, you have to dig in the Network
Connections area and find out why.
- Is the user’s Wi-Fi adapter able to connect
to the wireless network?
After seeing the message that networks are available, another
message should pop up with a message like "Connected to Coach,
Signal is Good." Once again, if the message doesn't pop up
you need to dig in Network Connections and find out why.
- Has the user’s wireless network connection
been assigned a valid IP address?
First, you need to know what a valid IP address is for this hot
spot. For all Coach Connect hot-spots the IP address will start
with 10.59.xx If instead, it starts with 169.xx you know that it's
not really connecting to the Internet.
- Can the user open a browser window and view an uncached
website?
If they have a valid IP address, they SHOULD be able to open
a browser and view websites. Make sure to try a website other
than the user's home page because that may exist in the computer's
local cache. Issuing a refresh command would also serve the purpose.
- Is the user’s browsing experience fast?
Even if they're connected and browsing, you're not done yet.
If the browsing speed is not significantly faster than a
dial-up connection, there's still something wrong!
- If you can't get past #1, 2, or 3, it's a pretty good bet the
problem is with the user's computer or adapter.
- If you get past
3 and are
stuck on 4, it's likely that the problem lies in the Wireless
hot-spot equipment. Resetting the Access Point may be in order.
- If you get
past #4 the problem may be with the main Internet connection.
You need to check to see if someone with a wired connection
can browse the Internet with the same ISP.
But wait! Those are only the 3 primary factors. There's a
LOT more:
- The end user’s computer operating system.
Macintosh OS X and Windows XP Professional are great. All others
could present challenges.
- The age of the computer.
- The type of USB port (1 or 2)
Although 2 is supposed to be backward compatible, we have found
that connecting a USB 2 device to a USB 1 results in very slow
browsing. A USB 2 device attached to a USB 2 port is very fast.
- The specific type/brand of adapter.
The adapter on the user's computer is clearly the weakest link
in the system and therefore, the most important part to get
right. The internal adapters rarely have the power to connect
to an Access Point in an outdoor environment like an RV park.
We have had much better success with the USB devices. Even
with a year of experience with them however, we cannot pinpoint
one brand that is the best. It depends on the operating system
of the computer, the age of the computer, the type of USB
port, and the version of the device drivers.
In general, try to match the 'vintage' of the adapter with
that of the computer and operating system.
'Don't give up,
try a different adapter.'
We've been amazed at this technique.
We had such good luck with the Zyair adapter, we used it for
everyone. One person's didn't work, so we tried using a Senao
and it worked great. The exact same Zyair worked just fine
on someone else's computer.
- The version of the drivers for the adapter and whether
they were properly installed.
We have had success more than once when the
adapter was completely uninstalled and reinstalled.
- Other network connections or settings on the user's computer.
Several times we have deleted a 'network bridge' to solve the
problem.
- Internet Explorer settings on the user's computer.
Many people who normally use dial up need to go into Internet
Explorer, Tools, Internet Options, Connections and click on
'Never Dial a Connection'
Another issue is found on Internet Options, Connections and
LAN settings: If 'Use a Proxy Server" is set to yes, they won't
be able to browse because there is no Proxy Server.
- Whether the user's computer has viruses or spyware.
One time we noticed when a particular person connected, the entire
system slowed down to a crawl. When she disconnected, all was
back to normal. We cleaned her computer of several viruses
and all was well.
- Whether any other user's computer on the network has viruses
or spyware.
- The distance from the access point
- The orientation of the adapter in relation to the access
point
- The obstructions or other interference between
the adapter and the access point.
One user in an RV park was online fine as
long as the sites beside him were empty.
When other coaches were parked there, he
could not connect. Another source of interference
is other 2.4ghz devices such as cordless
phones.
- Other possible Wireless Lans that may be conflicting with the
signal.
If another WLAN is in the vicinity and is using the same channel,
it can conflict with user's ability to browse.
- The prior network connection settings on
the user’s
computer
- The Firewall configuration on the User’s computer.
We saw one user unable to browse even though he had a valid IP
address. After fussing for a while, his firewall popped up
a message "WLAN detected, do you want me to TRUST it?" As soon
as we clicked the "Trust this SSID", all was well.
- The Firewall configuration on the main office
computer system
- The condition of the web server you are
trying to access.
Remember, just because you get the
'
Page cannot be displayed' message it doesn't necessarily mean it's your problem,
it could be the server for that page
is
down.
Try
another one.
- The condition of the World Wide Web
at any given time.
In one hot-spot, the user's complained
of slow browsing. This happened every
day between 5 and 6pm. We believe
it was due to overloaded conditions
on the Internet.
- The weather.
Water in the air can interfere with radio signals like Wi-Fi.
