Intel Wifi Link 5300 slow inbound speeds

I've recently realized that whenever I'm using the wireless on my np8662, I get roughly 1/3 of the inbound speed I get from plugging in with an ethernet cable. The outbound remains roughly the same. I'm running the latest drivers for xp, and I've tried several different networks, all using different routers, but my wireless remains somewhat pathetic. I'm about to test this on an Ubuntu livecd to rule out driver issues. Are there any known troubles with the wifi link 5300 in np8662s? Does anybody have any suggestions?

 

what are the actual speeds you are getting on wireless. if you're using a wireless g router it's not going to come near ethernet speeds, especially gigabit. if you're on an n router, it's my understanding that having another computer using b/g can cause it to slow down to those speeds.

 

I get about 4.5Mb/sec up and roughly 3-4Mb/sec down when I'm using wireless.
With ethernet I get about the same up speed and about 15Mb/sec down. Other computers using the same wireless get nearly the same speeds as the ethernet (maybe 1Mb/sec slower.) This problem is isolated to just my laptop, nobody else gets such specially abled wifi.

edit: forgot to mention everything I've tested has been on wireless g

 

sorry about that, i asked questions you already stated. it seems wrong that you're getting slower inbound than outbound. since we're talking Mb/s i'm assuming we're talking about using the internet. a firewall you have enabled may be slowing you down somehow. i'm just tossing out ideas, hopefully someone else will be in shortly to give you some good advice

 

yeah, I'm talking about the internet =P
And it is really odd :|

 

I imagine you have looked at your wifi adapter properties and made the correct config ...link speed duplex

 

do you think you could elaborate? I'm not as savvy as you think

 

unless you changed the default, you rarely ever half to adjust the duplex on the adapter, most are set to auto or full-duplex anyways.
Any other improper adapter settings would likely prevent you from connecting in the first place, but you'll want to indeed check that you're using g and not a/b (it will usually say in the connection details, or you'll know inherently if you're using a newer encryption scheme like WPA2)

As mentioned above, also check firewall settings, as well as for traces of viruses/bloatware hogging your connection (use taskmgr.exe to monitor in/out bound activity)

Try a speedtest (google "speedtest")

Also, make sure you've tested and controlled for distance; the further away you get from the access point, you'll notice a decrease in connection fidelity which means increased packet-resend/lag.
