Hello everybody

There are three drivers available for this adapter:

8188eu-aircrack-dkms-git
8188eu-dkms-git
8188eu-dkms

Have you tested any of these drivers yet?

If so, which one(s) ?

If not, that would be the place to start.

Many Realtek adapters require installing the drivers separately as the in kernel drivers aren't well developed yet.

Be sure to reboot after any driver installation.

Please post lsmod | sort before you install an alternate driver, and then post it again after installing any driver package (reboot first) .

Hi there.

I made several suggestions and requested you post further outputs when you opened your help request. It appears you have not been online since opening your request some days ago.

When suggestions are given and outputs are requested it is incumbent upon the OP to provide this information in a timely manner or your thread will be deemed abandoned.

I like to keep the networking section clear of abandoned posts that are left dangling. Otherwise, we simply get a bunch of new users tacking on "me too" to old stale posts that likely aren't even a related issue.

As such I am putting a one week countdown lock on your thread for you to respond and provide the requested outputs. A week and a half should be more than sufficient time to reply to any request for outputs for most anyone requesting assistance.

If your thread has been locked and you wish it reopened then please PM another moderator to reopen this thread. I am no longer accepting PM's from users as some users have abused this system and I no longer accept PM's from members.

If your issue has already been resolved, please revisit your thread and provide an update so that other users know how to fix a related problem in the future. Please do not open help requests only to abandon them and not provide some form of closure to your thread. Even if you simply gave up on your issue you should do the courteous thing by replying to your own help request and let others know that you no longer require assistance.

It's just the courteous thing to do, and helps keep our forum neat, tidy, and organized for users to find solutions easier.
