Default Mini 9 Wired and wireless not working - 02-09-2009, 08:41 PM

Day 6 with our refurb mini 9 with Ubuntu 8.04…still can't use it. Have wasted far too many hours trying to get ethernet card to work…no joy. Have spent days reading forum posts -- I've learned a lot (thanks everybody!) but haven't solved my issue. Can't connect wirelessly or wired. Ready to call it quits and send this thing back to Dell--please help!

The mini 9 sometimes recognizes the ethernet card, and sometimes it doesn't (under Network Tools). I can "see" and select my home network when I click on the blue bars…but I cannot access the internet, download system updates, etc. When I right-click on the blue bars and check Connection Information, sometimes I get IP and Sub-mask info and other times it's all zeros.

I tried plugging the ethernet cable into the mini 9 directly, and nothing worked -- either under "wired ethernet" or "PPPoE" settings.

I'm using a Westell VersaLink router/DSL modem. I've updated the firmware (based on advice from another post). I use Verizon DSL. I turned off encryption. Turned off MAC filtering…made my home network wide open for anybody to use (cuz hey, I can't!). Nothing worked.

Thinking maybe the router/modem was the problem, I went to Starbucks to use their wifi connection. I could see and select their connection…but couldn't get anywhere.

So now I'm stumped. If I'm getting blue bars, that tells me the wireless card is at least partially doing its job, right? I've tried every possible combination of settings on the mini 9 under "Network" and "Proxy", but nothing seems to work. When I try to query the ethernet card via "Network Tools" (both eth0 and eth1), a pop-up tells me there's nothing to configure.

I'm sure I've left some crucial detail out of this post, and I'm sorry if my frustration is coming through. I WANT to like this cool netbook and really want to like Ubuntu, but I cannot waste another hour or three or four to make zero progress. Please please help!

Thanks!

-Dan

Dan - how absolutely frustrating!

I, unfortunately, don't have many suggestions. Are you able to boot to the Ubuntu 8.10 Live CD (either via CD or on a USB stick)? I'd be curious to see if networking works in that. My wireless has always worked out of the box in 8.10 (although I have not tried wired.)

I know the wireless should work in Dell's 8.04, but...

Good luck!

Jeff

The only thing that concerns me with what you have posted is that Ubuntu "sometimes" recognises the networking device (which one?).

Otherwise, I suspect this is a software issue, which we chould be able to resolve. Linux apparently struggles with some routers due to DNS resolution issues.

First thing to check is that your wired network works (do 1 thing at a time):

Plug it into your router, then turn the Mini on.

Does it auto-connect? It often takes about 30secs to give you a "Connected to wired network" confirmation.

If it doesn't:

Does your router use DHCP or static IP?

I have never used the BIOS in my Mini - but go in there and have a look around to ensure that the ethernet (and wifi) are turned on (perhaps refurbished units are not checked as thoroughly?). It is either a 0 or 2 on the boot screen - can't remember which one.

It will be easier to work out what's going wrong if we use the Terminal, and you just copy and paste the results into here (use a USB stick to transfer to another computer if necessary). Again - plug in and turn on - then:

Code:
ifconfig
iwconfig
ping -c 3 208.67.219.101
ping -c 3 opendns.com
Those should hopefully lead us in the right direction... Just copy / paste here for us to review.

Sorry for the delay...had to wait til I got home from work.

To answer your questions:

Q: Does it auto-connect? It often takes about 30secs to give you a "Connected to wired network" confirmation.
- Answer: it appears to connect (wired network is selected when I click on the network icon...but still no internet joy)

Q: If it doesn't: Does your router use DHCP or static IP?
- Answer: the router uses DHCP; Verizon DSL assigns a dynamic IP whenever you connect. But here's a possible twist...Verizon requires a PPPoE connection.

Q: I have never used the BIOS in my Mini - but go in there and have a look around to ensure that the ethernet (and wifi) are turned on (perhaps refurbished units are not checked as thoroughly?). It is either a 0 or 2 on the boot screen - can't remember which one.
- Answer: it's 0. I checked. Both ethernet and WLAN enabled. I turned Bluetooth off while I was there as my mini9 has no Bluetooth.


OK, so here are the results of the four commands you asked me to type in Terminal.

This first set is with “Wired: Automatic Mode enabled”

I found this: http://www.westell.com/broadband-home-n ... teway.html
I presume this is your router. I haven't seen a full manual for it, but it looks like it is an ADSL modem, with an optional "uplink" port (ethernet) allowing it to become a standard DSL router to connect to another modem. I assume you connect it to the Mini with an ethernet patch cable, but not in the "uplink" port.

I think that you should not need to change anything on the Mini - all the PPPoE settings need to be done within the ADSL modem's settings page. I don't have a Verizon connection, but I don't really understand how an ADSL modem-router can require you to set the connection to Verizon from the computer directly; that is what the modem part of ADSL does. The "ipconfig" shows that the Mini is connecting (and acquires an IP address from the router), but is then unable to connect to the outside world.

1 other command that would be helpful:
Code:
route -n
This reveals the router's IP, so you can try pinging that. e.g. my route -n:
Code:
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth1
169.254.0.0     0.0.0.0         255.255.0.0     U     1000   0        0 eth1
0.0.0.0         192.168.1.1     0.0.0.0         UG    0      0        0 eth1
So I would use (to ping router and confirm connection):
Code:
ping -c 3 192.168.1.1
If that works - then the problem is clearly in the router settings rather than Ubuntu.

PS: Have you managed to get online with this modem-router with any computer?

For what it's worth, I recently became exasperated with the poor router performance of that exact model modem/router. I decided to use it as a modem only and leave routing/wireless duties to a Linksys router. I fiddled for hours and could not get the two to communicate right. I finally called Verizon support, told them what I was after, and in 15 minutes the two were setup properly.

(And the symptoms were very similar to what you're describing.)

If you have the option to borrow/buy a wireless router to see if that solves the problem, I'd suggest doing that. (And if you get the router from the right store and it doesn't solve the problem, you can return it.) Then call Verizon support and ask them to walk you through using the Westel unit as a modem only and the other unit as a router.

Good luck!

jej.514 -- I'd read similar complaints about the Westell modem/router elsewhere and saw that a number of people did what you did, creating a bridge between the Westell and a store-bought wireless router. Do you happen to remember the steps involved in disabling the router functions on the Westell and setting up the bridge? Thanks!

ugm6hr--thanks for continuing to work this!

I *wish* Verizon used equipment that nice…here's the 327w I'm using: http://www.westell.com/versalink-mod...327w15-06.html. Helpful, ain't it! I have the pdf manual (for what it's worth). I've been connecting the mini9 directly via ethernet cable…unplug it from the back of my desktop PC and plug it into the mini.

You said: "The "ipconfig" shows that the Mini is connecting (and acquires an IP address from the router), but is then unable to connect to the outside world." Yes--that's what's been so frustrating; thanks for confirming what I thought was the case.

And "Have you managed to get online with this modem-router with any computer?" -- yes, it's my home PC's connection to the outside world. Been using it for DSL service for 3 years or so…directly connected via ethernet cable to the LAN card in the desktop PC. This is the first time I've attempted to set up a wireless network in the house though.

Will run the queries you suggest when I get home tonight and post the results here. Thanks again! Going on 2 weeks with a Dell Mini9 that I can't use… Cheers!

- Dan

Make sure you try all this with a wired connection to the Mini first.

Wifi introduces a new layer of potential confusion. It is best to isolate where the problem is first.

And do you recall setting up your home computer to work with this?

Most (almost all) modem-routers require no setup on the computer at all. So once the connection is made from the router, just plugging it in should get you online from the computer. Hence, if your computer required tweaking, it would be useful to see these instructions to see whether we can translate them for the Mini.

OK, ran the further Terminal commands. sorry about the formatting/spacing - could not get it to display properly. The attached txt file has the same info.

I made sure all the router and network settings on my desktop PC were used on the mini. On my desktop (WinXP), I have 2 network connections active whenever I access the internet:
- Under "LAN or High-Speed Internet", Local Area Connection shows up and the device is the Broadcom ethernet card
- Under "Broadband", I have Verizon Online and the device is "WAN Miniport (PPPOE)"


I assume I also need two connections on the mini to make the Verizon DSL PPPoE connection. I can ping my router and I can open the configuration page in the mini's web browser. Beyond that, I'm stuck. Appreciate the help!
