However, there are two ways: to fix the wireless log page or to prevent users from using an apostrophe in SSID (not good).
Used an apostrophe in my SSID for years and years on different routers but had not any stability problems related on SSID name.
If the newest router causes stability problems with apostrophe when older models don't - maybe we should wait for Asus to fix this for ONE model, but not disable this for older devices.
I changed the client array to use " " instead of ' '. It will now cause an issue for anyone using " " in their SSIDs, but since it's less likely to happen than with single quotes, I felt it was worth the change.
If some client devices have problems with apostrophe in ssid name - so those are bad devices and they have to be thrown out of window.
Or, people will spend weeks trying to figure out why their device can't correct, blame everything on their network, spend a lot of time on the forums, for something that could be fixed in just a few minutes by using a more standard SSID.
The problem is that, initially, the 802.11 standards didn't clearly specify what was a legal character and what wasn't in an SSID, so everyone started interpreting it their way. The simplest solution is simply to avoid being overly creative, and sticking to a simple alphanumerical SSID.
