Basic Adhoc Network Problems
Adhoc network
problems sadly are a common issue and many people simply just
give up due to the problems they encounter when setting up the
connection or getting it to work reliably.
The Adhoc or computer
to computer type wireless network can be a convenient and cost
effective way to connect two or more computers together, but the
list of known problems can frustrate the most patient of us. We
have compiled a known list of problems with possible solutions.
A very common cause
of adhoc network problems is the version of software that came
with your Wifi network card, checkout your manufacturers website
and see if a more up to date version of the software is
available, many of these come with there own networking software
with easy to setup adhoc network software.
Cannot get an
adhoc network working from a USB network adapter
This can occur when a
computer only has USB 1 type ports, either add a USB 2 card or
install an internal network card if possible.
I get a connection but cannot browse
Have you enabled Windows ICS or Internet Connection Sharing?This
must be enabled first, even then we have found ICS to be quite
flaky and recommend a free product called AnalogX proxy server,
its very small and robust.
Try setting IP
addresses to static not DHCP otherwise it can take a long time
to find an address.
Make sure your firewall is set to allow browsing on port 80,
plus any other services you need such as FTP, SMTP etc, simple
way to test if the firewall is causing problems is to simply
disable and then test.
If you are using an
internet connection via PPPoE Make sure your computer has the
correct MTU network settings, firstly find your gateway address
on your client pc, (from the Start Menu, type CMD, then IPCONFIG)
Now type Ping -F -L 1500 xxx.xxx.xxx (type your gateway address
into xxx.xxx.xxx)
If you receive an error try pinging -F -L1450
what we need to achieve from this is a ping response and you
need your setting to be as close to 1500 as possible, so keep
going lower or higher until you find this number.
Note
if you get a ping response from 1500 this will not work for you
Once you have it you
need to enter the following into the registry
Go to
Regedit/HK_LOCAL_MACHINE/SYSTEM/CurrentControlSet
/Services/TCPIP/Parameters/Interfaces
Create a new DWORD value call it MTU, double click on it choose
the Decimal option and enter the MTU number you found earlier.
I have a connection but it keeps dropping How fast is
the connection you have chosen?
Try to slow the connection down, selecting B instead of G
will go from 54 to 11 mbps
Adhoc networks do have a place in networking, but only a
temporary one, I only ever use Adhoc as a last resort, the only
advantage of using Adhoc is convenience and cost, but as routers
are becoming cheaper it simply is not worth the hassle of using
it,
generally adhoc will
be slower, more problematic, the range will not be as good as a
wifi router, and of course you need to keep the host pc on
whenever another pc wishes to use the internet.
