Wireless Net

[sherlock ohms]

Having problems with communication between router and pc.. the signal seems to vary of its own accord..ranges from 'very good' to dropout, with no change in external environment.. also the link speed seems to be better when signal is low?..(200+Mbps with a very low signal, 52Mbps with a very good signal)..once again, i return to my usual state of confusion...

(netgear router and usb thingie) wnda3100 & wndr3300, approx 30ft between components

Would my being radioactive be a factor?

There are SO many factors that come into count, here's some I know of from personal experience:

1) Range. How far away is your unit?
2) Isolation, are there many metal items between you and the router? Lot's of concrete? Remember - WiFi works on 2.4 / 5 ghz, and up there...many things can "reflect" the signal.
3) Have you tried changing channels? Some channels have a lot of interference and noise issues, try setting another channel, you can do this in your routers setup.
4) Have you tried lowering your speed expectations? I can't imagine you having a 100 mbit internet connection (we barely have that here, and we consider ourselves ahead of the world if you are to believe the statistics) Therefor - you can also set a LIMIT on this - again in your routers setup, this often improves communication because of less packet loss
5) Are your router standing on a metal shelf? Try somewhere else.
6) Are there a lot of neighbors around? Do you live in an apartment complex with lots of apartments? I do - and they all have WiFi - which of course - causes interference problems, and changing channels away from the DEFAULT channel - often helps.
7) Other units also operate in the 2.4 ghz area, such as Bluetooth, some weather stations, Video-links and much more, when they're turned ON / OFF by people around you....your 2.4 ghz router WILL suffer...trust me! Again - experiment with channel settings + speed settings.

Hope that helps you out a bit

*Edit* If nothing of the above helps, you may want to consider getting an external WiFi antenna.

This IS a DIY forum after all - so why not build a Cantenna or a Bi-Quad? I've built a Bi-Quad (with too much success actually, because it received just about anyone even if directional)

..100Mbit?.. not even in the gardens surrounding that ball park.. I have a whopping ..wait for it.. 1.1Mb..on a good day..average around 900Kbps,until i run out of b/width..then 56Kbps.. the link speed from the router was more an afterthought than an issue, as it exceeds anything my ISP will ever throw at it.

I'll have a tinker with the channels etc.. at the moment i am on an open(unsecured) connection.. wondering if using WEP is gonna compound the problem?

Thanks for the suggestions JoOngle. ..i appreciate your time

sooo ...
with no obvious physical changes in the comp placement/environment the signal level goes to hell ? or is it just the transfer rate ?
yeah , i would suspect another signal gumming up the works .
however , if the signal level is dropping this could be due to the output of the wireless side crapping out .
i would try substituting a known good router .
for an off-the-shelf type i have had good luck with the linksys equipment .

the stability of the wireless side of your laptop is another thing to be proven out as well .
