Hello, I recently installed DD-WRT on my Asus RT-N66U.
Specifically: DD-WRT v3.0-r44251 big (08/28/20)
Whenever I enable WEP and try to connect to my network I run into two issues on different computers.
1. my modern MBP connects, but I don't get an IP address via DHCP.
If I specify one I still can't access anything.
2. on my old PowerBook G4 running 10.5 I simply get the error incorrect password despite the password being correct.
I have a password set, I clicked generate and all 4 keys populated, and I clicked apply at the bottom.
Is there a bug with WEP that causes this sort of an issue, or am I doing something wrong?
I had the exact same issue on an older Linksys router
As expected ethernet works fine, connecting and dhcp works fine without encryption.
Yes I know I shouldn't be using WEP.
This isn't for modern devices, and it's either WEP or nothing.
I'll be setting up a MAC filter and cranking the broadcast power all the way down.
The IEEE* 802.11n draft prohibits using high throughput with WEP or TKIP as the unicast cipher. If you use these encryption methods (for example, WEP, WPA-TKIP), your data rate will drop to 54 Mbps. The latest Intel® wireless adapter client drivers connect using a legacy IEEE 802.11g connection rather than failing to connect altogether, which complies with the IEEE 802.11n draft.
I didn't check the connection type before, but my modern MacBook probably switched to G automatically, while the older PowerBook just didn't know what to do since it's too old.
FYI! Even for old devices that only support WEP, if they at least have an ethernet port, you could use a wireless ethernet bridge as a wireless replacement and not have to resort to WEP. Even devices dating back 30 years ago, long before the internet, let alone wifi, can be made wireless using this technique.
I can break into your wep protected network in less than a minute. Can't you get a cheap usb nic?
No. And if I did I don’t think an operating system from 1999 and was last updated in 2001 would support wpa2.
You’d also have to break onto my property and potentially into my house to get the signal, get around the MAC address filter, and be there on a day when it’s turned on.
