You probably have leeches using your bandwidth since you have no security enabled.
If you have a cordless phone that is using the same broadcast frequency as your WLAN that can cause interference. Or if a neighbor has a WLAN set to the same channel as yours that may cause problems as well.
No leeches since I can monitor who is connected to my router. Also there is no interference. Computers are next to each other and I have selected the optimal channel so that connection is close to 100% from the computers to the router.
Any other ideas ? This must be configuration problem with either windows or the router !
Well in the mean time since your speeds suck even for wireless g I would switch over to those. Just set up your router to only broadcast in g mode. Granted this bites and I would through a fit and return it but if you can't you can whether the storm in g mode until they fix it.
On a side note 30 mbps seems low for what you draft n guys are spending. My super g mimo set up does that with a $25 normal super g card and will do 40 if I spend the $70 for a supger g mimo card. Granted my stuff is prolly no longer supported but at least it works.
To my surprise, I have found out that the transfer rate is capped out at 5mbps on a ad hoc xp based network. The radio is capable of 54Mbps G transfer rates but OS will not allow this. see for yourself open up task manager and look at the wireless transfer rate...im looking for a fix, reg hack to work around this problem.
The first thing you should understand is how speeds are measured and denoted. Speeds will be reported back in kilobits, kilobytes, megabits or megabytes per second. A common source of confusion is the difference between a bit and a byte. There are 8 bits in 1 byte, so if your transfer speeds are 12 megabits per second, you're really getting 1.5 megabytes per second (12 divided by 8). Some programs report back in bytes, some in bits, it's a matter of which program you're using.
The second thing you need to understand, is you will never get the full advertised speed on your wireless router. If the router says it is 54 megabits per second, you will likely only see half of that in real life situations. This is because of overhead and interference, which you can not get rid of. Even on 100 megabit wired connections, you will likely never see it's full capacity. Most people will see around 2-3 megabytes per second (18-24Mbps) on their 54Mbps (802.11g) router/AP's.
