Does anyone understand me?

Well i tried to contact netgear to help with this problem, but of course it was past the 90 day dead-line you have to use live phone support. Anyways, I'm using the RangeMax WPN824. On this website i see alot of comparisons in compatibility between the wireless router(WPN824) and another device. Would that other device be the ISP's cable box or A wireless PCI adapter? Anyways I'm guessing its the Adapter so i run a D-LinkAirPlus DWL-G520 adapter picking up the internet from the WPN824. My problem is that for christmas my siblings got new laptops for christmas and now we experience frequent drops. If i unplug the power from RangeMax and let it re-establish we will experience connectivity for a short period of time (usually 15-30 min.) then it will drop. Also When i hover my mouse over the default windows wireless network connection system tray icon it lists the speed as ONLY 11.0 Mbps.!!! Also when we do experience these drops both the windows and the D-LINK interface will list the connection as being good and signal strength excellent. however when i try to connect to the internet no webpages load and no music downloads. Ahh this sucks. Any help would be appreciated.

I understand u but I am no help as I have a simular problem as it seems others do here as well with 824. I am using it with a direct ppoe connection, no modem, and the router seems to clog after some time. repowering the router seems to fix for a bit, but now forever. I am hoping there is help here in this forum soon!!!!

I also recommend this thread: http://forum1.netgear.com/showthread.php?t=430
as I think this is the same problem that we have...

Seems to me that i can repower the Rangemax and use one computer(wireless) just fine but if i power up a laptop and try to browse on two computers at the same time i experience total internet failure. this sucks! especially since there are usually 5-7 computers that connect to my network on an average day. thats not including the direct cable hook up of the Xbox 360 and another direct cable hookup laptop. do i need a new product ? how do i get my network to run smoothly? Is the best advice to just pay a professional to do it right?

What is the manufacturer and model number of your modem?

On a wireless PC when you scan for networks what do you see? What wireless security are you using? Are you on cable or DSL? Is anyone using P2P or similar software regularly?

You could try turning off SPI in the router WAN Setup, and depending on your connection type and ISP your MTU might need adjusting;

A drop in wireless rates often indicates that other wireless networks may be operating on the same or near channels.

I went to that page Mug and Dr. TCP software does not work. I mean I set the MTU on a machine to 1492, but when I open up Dr. TCP again it reports the MTU at 576, which was the original default.

Is it worth while setting the mTu on all adapters in the lan to match the router? If so I will find another tool to do that...most of the ones I have seen have presets, and don't allow you to set direct, like WinXP manager and TuneUp Utils 2006. They just let you pick a type of connection and adjust the Mtu based on that. arg.

My understanding is that MTU is a system requirement, that is it needs to apply to the PC, the router, and all along the line to the point where the data you are after is coming from. Clearly you can only make changes to the PC and router. I believe Dr TCP checks the PC, not the router, and suggests an optimum value. An MTU of 576 is very low, the sort of value you might see with dial-up connections. Perhaps you are running a dial-up optimiser without realising it, if so it should be removed?

Are there other wireless networks operating in your area?

Who is your ISP?

Thanks again Mug, Dr TCP won't change the MTU (this software is from 2002!), there must be a command line change in XP I can use no? Before this PC was dial-up connected, so perhaps that's where the MTU setting came from...in fact all the machines on this lan are set that way. Now I just need a way to match the MTU to 1492, which is what my ISP says is optimun for thier service. The value does seem to be locked somehow.

Ps. I don't have a router, this is a cable service where they just throw a cable over the village huts and you have to drill a hole in the window frame to get it inside.

There are other wireless routers in huts around, but I am not using wireless right now, I have the 824 just wired....

thx

Yes, the point about other networks operating on same or adjacent channels is a valid point. I just got my 824v2 the other day, it replaces my previous router/access point set-up, which I have almost 2 years experience.

At any given moment a Windows Network Scan may show up to 3 other WLANs (my neighbors). If I were to set-up my old access point to the same channel as one of my neighbors, I could predictably duplicate the problem and connection will drop perioidically. Isolating the channel and no problems.

No problems so far with my 824v2, latest firmware.
Getting approximately 20 Mbits/sec WLAN to LAN measured throughput, 40 feet away, through one floor. Configuration: SSID Broadcast disabled, Channel 1, Mode g only, WPA-PSK TKIP.

If you have problems with your router, then one thing you can try is different combinations of settings, mainly channel and security. Unfortunately, sometimes router firmware has bugs, and no manufacturer is immune to that. Trying a different configuration may mean you can workaround a firmware bug. It isn't always the router at fault. Sometimes its the client hardware. I've seen client hardware that would, for example, work fine with WEP, but only partly work with WPA. Sometimes updating the driver software on the client PC can fix the issue.

Also, another common problem that often escapes attention but can cause all sorts of strange problems, is when your cable or dsl modem and your router are both configured with the same local IP address. In fact not only should they not have the same IP address, they shouldn't be on the same network either. For example, if your router is 192.168.1.x, then your cable or dsl modem should be on a network other than 192.168.1.x.

With a PC just connected to the cable, without the Netgear connected, and able to view web pages, type ipconfig /all at a command prompt and let us know what IP address you see for the gateway.
