Any advice on getting a netbook to connect to a network?

I bought an Asus netbook today, expecting, of course, to be able to connect to my home wireless network. So far, no go, after several hours of trying.

- I know that the network is up and running, because I can still connect with my other laptop.
- I am able to get the Asus to connect to the network through an Ethernet cable. Yes, I have unplugged the cable again after testing that.
- The Asus is able to detect the network, gives the right SSID, and tells me that the signal is "excellent".
- I'm pretty certain that I have the right encryption key - when I type in a different one, I get a message telling me it's not the right key. When I type in the right one, I get different error messages.
- I have 64-bit WEP for security, and that's set on both ends (though the Asus doesn't give options for other numbers of bits).
- The Asus uses Windows 7. When it fails to connect, it goes into a typically unhelpful Windows help screen that eventually tells me to reset the router, which of course makes no difference.

I haven't yet had a chance to see if I can connect to Wifi hotspots elsewhere, though there is an unsecured network here that I can see - when I try to connect to it, I get the same "Windows was unable to connect to..." message I get with my network.

By the way, my router is pretty old, and it's 802.11b. The Asus is supposed to be b/g/n.

Any ideas?

    Perseverance. Also try writing down all the settings from your other laptop and the asus to verify they match. Check and record the data from every "option" or "advanced setting" or similar button you encounter. Then try to delete all the connection information from the asus and re-enter it. I had similar problems with my Dell laptop a few years back and my acer last year.

    Good Luck.

    I'm going to go out a little later in the morning to see if I can get it to connect to other networks. I'm kinda hoping that I can't, so that the problem is in the ASUS, and not in my home network settings.

    It'd be a lot less frustrating if you could get rid of all that "To connect to a network, select the network you want to connect to and click 'connect'" Smile that keeps popping up each time I try something. I suppose that's a large part of what drives people to Linux.

    Speaking of Linux.. why not test the connection using a live distro tailored for the netbooks?

    With my eeepc I'm using easy peasy, and I'm happy with it. I installed it in a SD card, so the original windows is still there, even if I'm not using it anymore.

    www.geteasypeasy.com/

    Anyway you can boot a live distro from a USB pen, and check if your WiFi works.

    If you are happy with it get a SD card, install it, and get Brad's tools.

    Do you know if the router is configured to not broadcast the SSID?

    Windows has a feature(?) where it won't connect to a wireless network if that network isn't broadcasting the SSID, even if you enter the correct SSID in the network settings. In XP, the SSID has to be broadcast. In Vista (and I believe W7), there is a check-box somewhere in the network adapter settings for "Connect to this network even if BSSID isn't broadcast", or something to that effect. Checking this will automatically connect you without receiving the SSID.

    It's a good policy to not broadcast the SSID if possible, as it makes your network a little bit less visible to casual war drivers. With XP, you kind of have to deal with it. With Vista/W7, you need to find that check-box.

    on your router, check to see if your preamble is set to long, auto or short, (most likley it's set to auto or short) try setting it to long and see if you can connect. i ran into this a few years back (b router, b/g/n network dongle), changing mine to long fixed the problem.

    I had the same problem.· I was mistaking a letter for some other letter.· I believe legal letters are A through F.

    What letters or numbers could you be confusing any of the letters with?

    Thanks for all of the help.

    Okay, to answer all of this...

    - The router IS broadcasting the SSID. The network appears in the list of available networks on the netbook's network connection list, and I just double-checked in the router firmware, and yes, it's set to broadcast. I think I must have had some issue with that in the past, because I know once upon a time I tried it without broadcasting, for security's sake, but something stopped working. I also do see the checkbox on the netbook for·connecting to networks that are not broadcasting their SSIDs, but I shouldn't need that, as I can see this network right there in the list. I dunno, maybe I should try it anyway.

    - The preamble is set to "long", which is the default for this router. I checked that in the router firmware just now, to make certain.

    - I don't think that my problem has to do with typing in the wrong encryption key. As I said, when I type in a key that I know to be incorrect, I get a message clearly saying it's not correct. When I type in what I think is the proper key, I don't get that message, but it still doesn't connect. I don't have any letters past "F" in the key I'm typing in.

    I'd consider using a Linux test to make sure that the wireless really works, but I'm nowhere near that point yet. These things are supposed to work correctly out of the box. I'm no network jockey, but I'm certainly not so stupid as to be unable to follow the basic directions to get a netbook going. I know how to log onto my router to check and change the settings, and I know what a WEP key is, and what an SSID is. The basic directions assume you don't know any of that. It took me about 30 seconds to verify that my preamble is set to "long", so I don't think that the problem is me. Surely it's not this difficult for everyone.

    The most likely possibilities seem to me to be that·either

    - my router is so old that there's something hidden in its settings that just doesn't work with 2010 netbooks, or

    -·there's something in my antivirus/network protection software that's blocking the connection. I'm using (gasp) Norton's (yeah, I know...). But I tried temporarily turning off the network protection and then connecting, and it made no difference at all.

    I think that trying to connect to a different network will tell me something, and that's what I'm going to try next. If it won't connect to those either, then there's something wrong with the netbook, and I'm not going to change any of my network settings here (because I know that the moment I do that, I'll have to go through all of this again to get my laptop back on the network). I guess·if it DOES connect to those other networks, then the next step will be to temporarily turn off my network's protection, and see if I can connect then.

    I've used my Asus eeePC all over North America both in its original linux form and after changing over to XP. Very reliable connecting at home and at various customer, hotel and freebie wireless sites.

    I think you're on the right track to check another wireless site, perhaps a friend's place or a local hotel. The other test would be to bring in another "foreign" laptop and see if it will connect to your router.

    Cheers,

    Okay, I'm at work now, using a public access spot here, and after a couple of little hiccups, it's working just fine. I'm getting my email, it connects to the net, and Skype works fine. It must be something in the interaction between the netbook and my home network. Of course that's hard to diagnose, but it's also something I can live with - I've got two other computers that work just fine at home, and this one seems to work just fine on the road.

    I'm still open to ideas for the home setup. Thanks for the help so far.

    I had this issue with Verizon.· They upgraded the firmware and when it doesn't take they tell you to buy a new one.

    We bought a DSI and both Gamestop and Bestbuy said it only worked with Linksys and FIOS.· They had a list of routers it was compatible with.

    I bought a Netgear adapter for a computer and either it was bad from the beginning or it doesn't work with Dell because it was 25 feet away from the router and it said 'no signal'.

    Yeah, there's that. I bought this one in about 2001 or 2002, I think, which makes it an antique. I just hate messing with things that work fine.

    Just a side note:
    WEP is not secure, so you can consider an upgrade worth the time for the sake of security.

    Noooooooooo! Don't suggest that. I love people who have WEP networks. They provide me hours of entertainment when I travel. With the latest aircrack tools you can generally poke a hole in WEP in less than 2 minutes.

    Once you're in, a neat trick is to do an nmap scan of their networks looking for printers. After determining the manufacturer of any printers on the network you can knock up an "official" looking printer status page and leave them a message with the printer stating it is low on water. That or a ransom note for the tins of anchovy in the cupboards signed the cat.

    Additionally on networks with exposed shared drives, new folders sometimes appear containing old BBC videos of Led Zeppelin. Dunno how that happens. Must have a virus or something..

    On your home network, try disabling WEP and leave the network unsecured for a few minutes and see if you can connect. If you really want to be paranoid, disconnect everything else from the network while you do the test (or leave a printer on for the cat).

    Once you've done the test, put security back on.

    This will get you to the "lowest common denominator", and if it doesn't work, it's time to splurge the $50 bucks for a new access point.

    Okay, okay, I'll look into getting a new router. The firmware in the one I've got gives only WEP for security - there isn't any WPA or whatever - and when I installed it, I was reading all this stuff about how people leave their networks with no security at all, so I thought I was being smart by setting up WEP. I bought the thing 8 or 9 years ago, I think. Maybe even longer ago than that.

    It looks like WPA and WPA2 are the standards now, right?
    ===================
    I just set up the FTDI drivers and RealTerm on the netbook, and that went as smooth as silk. Among other things, it's going to be attached to the receivers for my XBee rocket telemetry gizmos, and it looks like that's going to be pretty straightforward to set up.

    You can plug a second router into the first router.· The address will be .01 or something in addition to the regular address, and as long as it is configured it should work.· You don't have to get rid of everything.

    Why would you do this? Adding another level of complexity to an already problematic network installation? Maybe for a quick test. Maybe.

    The fewer devices, the better, and especially when they are in "series" (or more properly "cascaded"). Each one adds latency and potential for other nasties.

    Verizon only gives us a Wireless G router for FIOS even though we have a Wireless N which we need for range since Wireless N has two or three antennas.· I honestly don't know why they didn't just set up my Wireless N router and keep their Wireless G.

    I haven't noticed any latency problems.

    I recently got a new netbook, and I installed the netbook version of Ubuntu. It seems to work better than the original windows version (faster, more efficient screen usage, and a longer battery life). I didn't do any quantitative comparisons though.

    Hmm... I am on my new Acer netbook right now, and I know that I haven't had any problems connecting to our wep "secure" smile.gif network.
    When you first booted the computer and went through all the win7 setup steps, did you select a default network? I did, and it automatically connects every single time.

    This may be a stupid and insulting suggestion, but be sure you have your wireless enabled. For my netbook, there's a little slide switch on the front edge of the netbook, which enables and disables the wireless.

    I don't mind the suggestion (how many thousands of times have we seen the problem turn out to be the most obvious thing?), but that's not it. Wireless is enabled on both the netbook and router side. Again, I'm seeing my network, and getting a report of "excellent" signal strength, but not able to connect. And it has connected just fine to a couple of public WiFi hotspots without any trouble.

    When I went through the Win 7 setup steps, I tried to select my network as the default, and it had the same glitch that I had when I came back after setup and tried to connect.

    I think I'm going to skip right to getting a more modern router, given the security concerns and the fact that I'm a couple of generations out of date (and 802.11n routers run well under $100).

    I did set up all sorts of other stuff (Thunderbird, MS Office, Propeller and Arduino environments) on the netbook today, and I'm very pleased with it. Other than not being able to connect to my home network, everything works very smoothly, and faster than I'd have expected, given all the heat netbooks take for being underpowered. New hardware installation (serial-USB converters, Propplugs etc.) happens noticeably faster than on my desktop (which is only about two and a half years old).

    Thanks for the suggestion, but no, it defaults to "both" (long and short). The router is using "long". I suppose I could check to see if the netbook's side could be set to just plain "long", but it's probably a moot point, as I just ordered a new router this morning. I'm taking this as a sign that I should enter the 21st century now.

    BTW, what's a preamble?

    BTW, what's a preamble?
    The preamble is used to communicate to the receiver that data is on its way. Technically speaking, it is the first portion of the Physical Layer Convergence Protocol/Procedure (PLCP) Protocol Data Unit (PDU). The preamble allows the receiver to acquire the wireless signal and synchronize itself with the transmitter. A header is the remaining portion and contains additional information identifying the modulation scheme, transmission rate and length of time to transmit an entire data frame.
    Long Preamble:
    • Compatible with legacy IEEE* 802.11 systems operating at 1 and 2 Mbps (Megabits per second)
    • PLCP with long preamble is transmitted at 1 Mbps regardless of transmit rate of data frames
    • Total Long Preamble transfer time is a constant at 192 usec (microseconds)
    Short Preamble:
    • Not compatible with legacy IEEE 802.11 systems operating at 1 and 2 Mbps
    • PLCP with short preamble: Preamble is transmitted at 1 Mbps and header at 2 Mbps
    • Total Long Preamble transfer time is a constant at 96 usec (microseconds)
    What does this all mean to the end user?

    Most access points (AP) and broadband·Wi-Fi routers are configured for a Long Preamble or have a setting that automatically detects the preamble and adjusts accordingly. A majority of client·Wi-Fi adapters should also be pre-configured in the same manner. This is done as a precautionary measure for networks that may still employ legacy devices.

    I have the Acer Aspireone. Bought myself the Belkin wireless and hooked it up to my older router. Set my key and up I went!

    Now the funny part is that I bought also a Belkin usb antenna for my other laptops, and they have a hard time connecting! It drops a lot.
    My little netbook, is just humming along...

    For you, my bet is that the OLD wireless router is the culprit...
    You could purchase a new one at "wallmart" and if it does work right away..keep it, if not then, just return it... wink.gif

    Follow-up: I bought a refurbished Linksys 802.11n router. It arrived today. I just set it up, and it works immediately, with the netbook, no problem at all. The hardest part of getting it set up was reaching around behind my computer desk to plug it in.

    I guess the lesson really is "keep up with the times".

    Oh, and so I'm not using WEP anymore, so the only odd things coming out of my printer should be odd things that I sent it myself.
