Fluctuating Connection Speeds.

My questions relates to the fluctuating connections speeds between my router and my laptop.

I have a small wireless home network connected to a USR 9106 router. My internet connection is a 2Mbps ADSL provided by Etisalat in the UAE. My laptop is a 6 month old LG LW60.

Till a week ago I did not notice any perceptible change in the connection speeds between the laptop and the router. It stayed steady at 54 Mbps if I was sitting in the same room as the router but went down if i went to other rooms, possible because of other interferences. Now I notice that the speed fluctuates persistently between 24 and 54 Mbps and sometimes will go down as low as 1 Mbps. Theorectically this should not affect the speed at which I connect to the net as THAT connection is at just 2Mbps but as soon as the connection speed between the router and the laptop falls it affects my download speeds (Utorrent will show 0 download speed) and surfing ability. Web pages will not open and I won't be able to access the mail servers.

I want to know where the problem is most likely to lie. Is it the router/ laptop or the ISP that is most likely to be the culprit and how can I pinpoint exactly which of the three it is. I have tried troubleshooting the router (resetting/moving it about etc) but that has not worked. I did talk to the ISP but they say that there is nothing wrong with the line and that leaves the laptop but I'm pretty sure that nothing has changed on my laptop since last week.

Would appreciate any advice on how to fix this problem.

Another question I have deals with my daughter's sony PSP. We just bought it a few weeks ago and I've been trying to get it to connect to the wireless network to no avail. I've input all the settings correctly in various permutations and combinations (with WEP/without WEP; manually inputting settings/ assigning IP adress etc etc) but I have never been able to connect. I usually get the error saying "check security settings" even while trying to connect after turning off WEP in the router (yes, I've turned the router off after doing that and then restarted that). What am I doing wrong? Or not doing?

Last quetion: somewhat related to the above. somewhere on the net I read that the PSP would connect to a 802.11/b network  not g. I have not been able to figure out where to check or change this connection in my router's configuration (USR 9106).

Thank you in advance!

hi there

the foremost possibilty might be that there are some electrical interference inside ur home i mean electrical fluctuations or maybe also some electrical fluctuations which might be causing the highs and lows in the speed.

and also check if the power adapter of the router is ok or try to change the power adapter and see if this resolves as i had been having issues with my adsl modem because of the power adapter supplying power to the adsl modem.

and This router from U.S. Robotics is another all-in-one device featuring ADSL modem, router, 802.11g wireless and a four port Ethernet switch

and i have come across this on the web

The Sony PSP contains 2 Taiwan manufactured Wi-Fi chips designed by Marvell Semiconductor.  The model numbers are 88W8380 (MAC) and 88W8010 (RF transceiver).  The chips are listed on this webpage: http://www.edepot.com/reviews_sony_psp.html 

The 88W8010 is an upgraded (802.11g) version of 88W8000 (which only supports 802.11b).  So this chip is fine. The one in question is 88W8380.  If it is based on 88W8300, then it only supports 802.11b.  But if it is based on 88W8310, then it is 802.11g capable (54Mbps, about five times faster than 11Mbps of 802.11b).  The 88W8310 chip also support 802.11i and 802.11e, which is AES (WPA) and QoS (quality of service). Maybe someone has more info on the 88W8380 chip.  If it is based on 88W8310 (not 88W8300), then the PSP actually supports 802.11g, but not activated

Yeah I have a router that you can specify (Mixed mode)  802.11 g/b signal but my psp will not work unless I set the router to strictly 802.11 b.......As far as were to change it I'm sure with this model.
