I cannot even detect my wireless network, which I know is running (I have other devices connected).

For what it's worth, I am coming from Linux Mint (cinnamon). I had this same issue when I tried installing Ubuntu 12.10, Fedora, and even just Debian. I eventually installed linux mint, and I could connect to the internet right off the bat. I would prefer to use ubuntu over linux mint, however, otherwise I would stay there (considering the wireless works without issue)

I hate to keep bumping my own thread -- but I hate to not be able to use my laptop at school even more :)

As an update: I cannot connect to the internet through an ethernet cable either.

Your thread title refers to wireless however your details are for ethernet:

Can you please run and post:

Code:

---

lspci -nn | grep 0280

Hello again, chili.

I just found that command laying around on the forums so I used it in hopes that it'd help some how.

Code:

---

lspci -nn | grep 0280
02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01)

---

I have tried downloading the RTL8188CE from my PC, then installing on the laptop. It did not work.

Your device is covered by the driver rtl8192ce in 12.10. Does the module exist in 12.04? Please run and post:

Code:

---

modinfo rtl8192ce | grep 8176

---

modinfo rtl8192ce | grep 8176
alias: pci:v000010ECd00008176sv*sd*bc*sc*i*

That suggests you have a working driver that claims your device. Is an interface created, ideally wlan0?

Code:

---

iwconfig

---

Is the switch on?

Code:

---

rfkill list all

---

Are there any interesting messages in the logs?

Code:

---

dmesg | grep -e wlan -e rtl

---

Code:

---

iwconfig
lo        no wireless extensions.

---

Code:

---

rfkill list all

---

(no results)

Code:

---

dmesg | grep -e wlan -e rtl
