Unable to access web. TP-LINK TL-WN725N wifi USB dongle

[exekutive]

I'm fairly computer savvy, but still super new to Linux so please bear with me.

The adapter info: http://wikidevi.com/wiki/TP-LINK_TL-WN725N_v2
Ubuntu 13

I downloaded the driver zip from https://github.com/lwfinger/rtl8188eu
Copied the bin file: sudo cp rtl8188eufw.bin /lib/firmware/rtlwifi/
"make all", then "make install"

The installation appeared to work and Ubuntu now recognises the device. I am also able to connect to my home wifi network, and obtain a valid IP address from my ISP. However, if I point my browser to google.com, I just get "This web page is not available". Punching in google's IP address doesn't work either. Pinging gets "unknown host google.com". The little status icon shows no reception "bars", even when the computer is right beside router.

Any ideas? Thanks for your attention.

May we please see the result of these terminal commands?

iwconfig
dmesg | grep rtl
nm-tool

Thanks.

By the way, the blue status light on the dongle does flash when it's plugged in.

I should also add that the device works perfectly in the Windows XP environment.

Thanks again for your interest.

It looks pretty solid so far! Are connected to a cable or DSL modem? Is authentication required; i.e. a username and password? Can you ping the gateway?

ping -c3 154.5.220.1
ping -c3 75.153.176.9
ping -c3 8.8.8.8

[exekutive]

Zyxel VSG1432 DSL modem via Apple Airport wifi access point. Both in bridge mode (ie DHCP turned off). No authentication required.

All three "Destination Host Unreachable".

[chili555]

What addresses, etc. do you get in Windows? Are there any clues here?

cat /var/log/syslog grep -e wlan -e etwork

If DHCP is turned off in both devices, where do you get this number?

IPv4 Settings:
Address: 154.5.220.92

Is it a static address provided by your ISP?

[exekutive]

It is a dynamic IP assigned by my ISP. I would get a similar one in Windows. The output to your cat command is extremely long. Do you want me to post the entire thing?

[chili555]

Let's shorten it up:

cat /var/log/syslog grep -e wlan -e etwork | tail -n20

It is a dynamic IP assigned by my ISP. I would get a similar one in Windows.

May we see it, please?
