Few days back while I follow my colleague went to upper penang road for some troubleshooting.
I have do some random wifi detect over my laptop, and guess what, I detect my ex-company wifi, the signal from so far still able to detect.
Still have 1 to 2 bar if signal, and manage to connected, and login with my own ID (My current company are the their Wifi Internet service provider)
I try to surf my own website, but the loading a bit slow, yet still faster then lousy maxis boardband 3G connection. (My experience with Maxis: Maxis lousy service, Maxis Suxxx Again, Maxis disapointed me again)
