RTL8187B + Dlink DI-524 give slow internet connection

[wzwilliam]

Hello everybody. I've just installed Ubuntu 9.10 in my laptop. Everything works fine except for my wireless. It works, but much, very much slower the through RJ45, which is perfectly ok. When using wireless i can't even connect to any online messaging service and I need to reload pages oftenly. My security setting is WEP 128 bits ASCII and since I'm trying to follow the format suggested on the thread "HOWTO post a Wireless issue" I'll try to provide the infos like requested on it. Thanks in advance!

Laptop brand and model (I'm from Brasil, so it's a brasilian model)

Semp Toshiba IS 1412

Thank you for answeting, chili555.

after

sudo iwlist wlan0 rate 54M
it gives me

iwlist: command `rate' needs fewer arguments (max 0)


Did it stick? If not:
sudo ifconfig wlan0 down
sudo iwlist wlan0 rate 54M
sudo ifconfig wlan0 up
iwconfigHow about now? Is surfing faster?

no, still as slow as before and even after this procedure it looks like the same results before:

some relation with the "fewer arguments", maybe?

[chili555]

Oops! Sorry. I mean:
sudo iwconfig wlan0 rate 54M

[wzwilliam]

now the Bit rate properly changed to 54 Mb/s, but now when i try to connect it only keeps me asking for the password after a few seconds.

[chili555]

I wonder what the kernel has to say about this. Please post:

It may be obvious but i forgot to tell that since the password request is looping, i can't coneect through wireless at all. Also, I guess you must be expecting that, but since I have little experience with linux, it can be useful pointing out that the terms wlan and rtl8 are in red on the terminal output.

It looks like it is asking the router for a response and the router is silent, so it times out. Have you tried resetting the router by unplugging it and plugging it back in? Is the router set to 802.11 B or G, or even better Auto speeds? Are you being asked for the WEP key? Is there MAC address filtering on the router?

[wzwilliam]

Unplugging and plugging it back won't be possible right now; *doing it through the management interface will cause the same effects?
The router is set to mixed mode, b and g, with tx rates set to auto.
Yes, I'm being asked for the WEP key, which just keeps being asked again after a few seconds in some kind of looping.
No, theres no filter of any kind being used in the router.

* No, it doesn't. I'll try thw unplug/plug as soon as I can and post the results right after that.

[wzwilliam]

I'm sorry for taking too long to answer. Unplugged and plugged back the router's power cable. The strange thing is that the wireless connection appeared as connected but i had no data transfer. Websites didn't load, messengers didn't connect, nothing. Then I tried the command ifconfig wlan0 down/up and the wireless connection started the looping the WEP key asking again without connecting. Is there a next step?

[chili555]

How many characters does your WEP key have? I noticed you said it's ASCII, which is a bit rare, but not impossible. Are you trying to connect with the ethernet cable detached? Network Manager will not use wireless if wired is available.

Please run:
sudo tail -n25 /var/log/syslogTry to find where the wireless tries and fails and post about ten lines up to and including that point.

Since your wireless device sees your network and tries to connect, I am fairly sure the card and driver are working properly.

[wzwilliam]

13 characters.

The strange thing is that this AP the laptop is trying to connect to is not mine. Is it normal?

[chili555]

The whole purpose of Network Manager is for you to specify the known, trusted network you want to connect to. Do you see your network when you click the Network Manager icon? Do you select yours and still try to connect to .net coronel ezequiel 3481-3762? It looks as if that network has WPA and you are saying you have WEP so it's not going to connect. Please see attached. In the example, I know I want to connect to 'GBR1' so that's the network I click.

[wzwilliam]

Yes, my network (Vila) appears on Network Manager, I'm correctly selecting it and, since it asks for the WEP key for it, I think the wireless card is trying to connect to it, bu after that it takes a while and asks for the key again. I'm attaching the images.

[chili555]

How many characters is it? ASCII is rare.

[wzwilliam]

13 characters. Do you think I should try to change the type of key?

[chili555]

13 characters. Do you think I should try to change the type of key?Not yet.

Please try right-clicking the Network Manager icon and select Edit Connections. Click the Wireless tab and select your network, Auto Vila. Click Edit and click the Wireless Security tab and fill in your WEP key and make sure the Connect Automatically box is checked. Click Apply and see if you connect.

If not, let's see:
sudo tail -n25 /var/log/syslogPost the part where it fails this time.

13 characters is correct for ASCII. Do you have an option to change to HEX in the router if everything else fails?

[wzwilliam]

Done, but everything is still the same.

And yes, I have the HEX option in my router.

[chili555]

I suggest you try HEX and, if it fails, just temporarily, unencrypted. Don't leave your system unencrypted for more that a few moments; just long enough to learn if it connects or not.

If you do:
cat /etc/network/interfacesdoes it contain more than the loopback stanzas?

[wzwilliam]

Hexadecimals give the same results than WEP. No security stablishes connection when the computer starts, but with terribly low speeds. If I disconnect the wireless card in the meantime, I can't reconnect.

Result of cat:
auto lo
iface lo inet loopback

[chili555]

I feel like we have done everything we can do to coax the native driver to life and it has not responded. I am sorry.

I think the next step is ndiswrapper. I saw this: https://help.ubuntu.com/community/HardwareSupportComponentsWirelessNetworkCardsRealT ek
The rtl8187 driver is very slow and have some problems but it works for this card in fact. Use ndiswrapper with Win98 driver from here on Hardy or lower. Install instructions here. Ndiswrapper info here (search for 0bda:8189). Linux USB ID here. Inside Gateway ML6720. Apparently connected to USB EHCI.Are you up to trying ndiswrapper?

[wzwilliam]

Whatever works. I just don't wanna have to unninstall ubuntu again just because of wireless.

[chili555]

For your reference, here is the guide I am following, but I have tried to simplify it a bit and use more modern, Karmic methods.

http://quilombo.wordpress.com/2008/03/07/realtek-rtl8187b-working-in-ubuntu-710-using-ndiswrapper/

I will boot into Karmic now, be back in a few. In the meantime, do:
sudo apt-get install ndisgtk

[chili555]

When you installed ndisgtk, it will have added all the dependencies. Now, let's get the native driver blacklisted:
sudo su
ifconfig wlan0 down
rmmod -f rtl8187
echo "blacklist rtl8187" >> /etc/modprobe.d/blacklist.conf
exitNow, let's find and extract the Windows driver files. Go here: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=1&Level=6&Conn=5&DownTypeID=3&GetDown=false&Downloads=true

Scroll down to RTL8187B and download the Windows driver package.By default, downloads go to your desktop. Right-click the zip file and select Extract Here.

Now, we are ready to install. Open System > Administration > Windows Wireless Drivers and click Install New Driver. Browse to Desktop/RTL8187B_Drv_XP_5.1160.0415.2009_Win7_62.1181.1105 .2009_UI_1.00.0145.ALL.L/RTL8187B/WinXP and point to net8187b.inf. Please post back with any errors or problems.

I think you can skip the step of Configure Network; I hope Network Manager will do all that for us.

Does Network Manager see your network now? Can you connect?

[wzwilliam]

Yes, now everything is working perfectly! Connected normally right now using Network Manager, security set to WEP 64bits HEX. I used primarly the info on the link you posted earlier to set things up.
I just have one last question: how can i configure the wlan0 to start automatically with ubuntu?

[chili555]

Wow! Great! I have a couple of guys watching this thread and they will be helped, too. I am very glad for you.

Right-click the Network manager icon and select Edit Connections. Select Wireless and edit Auto Vila. Make sure that Connect Automatically is checked.

Can you please mark this as Solved?

[wzwilliam]

Perfectly!

chilli555, thank you very much for your time, patience and knowledge!

[cayman.n2o]

Hey guys!
I found this topic googling.
I have the same router and the same problem. My laptop is FSC Amilo pa 3553 with Atheros AR928x.
Since I am total noob when it comes to linux and console, could someone just form commands for me, for solving this problem? Please!!!
