When it comes to understanding your Wi-Fi and/or cellular signal strength, sometimes Apple's simple three little curved lines and five little dots in the Status Bar are enough for the average user. For those that are a little more savvy in the world of wireless technologies, they might wish to have an RSSI (received signal strength indication) indicator for a more accurate depiction of their signal strength.
Two simple new tweaks by iOS developer Joshposh2012 are now available for free in Cydia called Numeric Wifi Enabler
and Numeric GSM Enabler
, and installing each, or both, of these tweaks will change the cellular and Wi-Fi signal strength indicators to RSSI meters so you can have a better understanding of your signal strength.
Shown above, you can see Numeric Wifi Enabler, which as the name implies, shows your Wi-Fi signal strength numerically, with -0 being the best wireless signal connection, and -100 being the worst wireless signal connection. This tweak adds a preferences pane to the Settings application where you can easily enable or disable the tweak on demand:
Numeric GSM Enabler does almost the same thing, but it shows your cellular signal strength numerically, rather than your Wi-Fi signal strength. With the cellular version of this tweak, -47 is considered the best signal strength, and -130 is considered the worst:
Numeric GSM Enabler also adds a preferences pane to the Settings application, where you can easily enable or disable the tweak on demand:
These are both fairly simple jailbreak tweaks, and they're an easy way to enable the numeric RSSI indicators rather than having the GUI-style signal strength indicators that give you only about half of the information you want. They work together if you want to install both of them, or you can install them separately.
If you want to grab either of these tweaks, they're available for free in Cydia's BigBoss repository.
