Perhaps you should have her evaluated by a behaviorist or trainer to determine exactly what she is doing and why she is doing it
in general the most practical advise. The problem with anty diagnose that relies on the observation of the owner is it is natural biaed observation and therefore it will result in a biased diagnose and solution that is only as good as the observation. getting and expert objective observation is important.
A puppy needs to learn bite inhabition. If you are nipped make a loud noise to startle the pup.I usually growl "NO" in as deep a voice as I can muster.After a few times of this they usually do not bite as hard as they did.
Alway good advice especial with younger puppies but by the age if six months it may be too late to teach this. This is one of the most critical things however owners have a responsibility to teach there dogs. All dogs at some time or anouther will feel the need to bite. Bite inibition is the difference between a damaging bite and a potentially euthanized dog and no damage. Teaching bite inihibition is literally a life saver for dogs.
Bite Inhibition how to teach it
In the link Above it gives a chart of assessment of bite injuries what if any injuries has the dog caused? This is the biggest indicator of success in treatment. Not because a dog that does not cause injury is easier to modify behavior because it is not. It is because with a dog that does cause injuries one can simply not train for all circumstances because of the risks, which means in the end that if you decided to keep a dog capable and inclination to cause injuries that there are going to be some situtation that you will just have to manage.
I can't believe a 6 month Basset is 'biting' as in biting as they aren't aggressive, or none of ours have been!
Generalizing breed traits to an indvidual especially when it comes to biting is not a good idea. ther are plenty of ill tempered bassets out their capable of causing a great deal of damage.
The question is whether the dogs behavior is simply because of its age, adolescence and biological process like teething which tend to make dogs this age more mouthy to begin with, Without actual observing a number of such interaction between the dog and the owners family it is not possible to tell which makes Terry advice all the more appropreate.
Some thing unrealted that can help. Exercise and mental stimulation, Is the puppy getting enough of these. Many people assume basset and more so basset puppies are couch potatoes which is far from the truth. With out enough mental and physical stimulation the will developed a whole host of behavioral problems including distructive behaviors.
Let us deal with some of the problems individually.
If we try to ignore her or tell her no she just comes right after us and if you walk away she bites us on our ankels
Ignoring behavior works through a process called extinction. That is behaviors that are not reward tend to end. So people assume it is a simple and easy to end problem behaviors by this method It is not. Especial with behavior that often this type of biting is associated with. which fall under the general catagory of "attention seeking behavior". What it means is that these behavior have been reward with attion in the past. Keep in mind often what we humans think as punishment the dogs veiw as a reward. Ie dogs jump up greet we push the dog down or knee it in the chest etc that interaction is attention for the dog and many dogs will view it as a reward" When discussing reward and punishment what is important is how the dog reacts to it. If a action is truely punishment the dog will engage in the behavior that resulted in it less if not then it is not punishing for the dog.
Lets get back to extinction. Simply ignoring a behavior for which the dog has been rewarded in the past is not going to result in the dog easily giving up the behavior. What occurs is called and extinctition burst in which the behavior gets worse much worse before it stops. The following is the most common analogy to explain. You get into an elevator and push a button for the floor you want. Nothing happens, what do you do. Get out and take the stairs? No you push the button again harder, longer, faster, different pattern. Try a different button. but not give up. You may give up that time. But next time you Face the choice of elevators or stairs you will chose the elevator again. Same thing happens with the dog. You need to be prepared for this when using this technique because if you Resort to your previous actions that are actual reward for the dog all you have done is teach the dog simply to be more more persistant. So simply ignoring a behavior and expecting to end a behavior is extremely difficult to accoplish and not one I would recommend on its own. But it is apporiate as part of a more comprehensive plan.
The problem with looking at any problem behavior as something you simply want to stop is it does not address why the behavior is occung in the first place. In most cases these behaviors are attention seeking behaviors. The atttention the dog desires does not end even if you are succesfull in ending the behavior. What end up happening more often than not is that the dog learns, picks-up and even more obnoxious behavior. Rather than thinging about what you don't want to do focus on training the dog an appropriate behavior. Ie sitting still when you walk by as opposed to bitting ankles etc.

Stopping Negative Behavior Positively
We have a kennel and put her in there when she's really biting and not stopping,but we don't want to keep her in the kennel long
A time out does not need be a prolonged period of time to be effective. What it need to be is consitently applied. by all memebers of the household. The idea of using punishment However can be dificult for humans and I quessing that it true in your case as well. Keep in mind it takes consistence inorder for dogs to learn, If hehavior a always results in consequence c then quiglif if the dog does not like consequence c behavior a stops. However as what happens most times is Behavior A results in consequence c sometimes consequence b at other with hussbad it is consequence x and teeager#1 consequence y the dogs responce is not going to be consistent either. So in the regard if you have trouble with using time-out ie punishing the dog the don't Only reward the dog. just make that reward soamething the dog does not want. Don't Punished the dog with crate confinement but instead rewards the dog with 5 minutes of alone time in his crate, It may seem like splitting hairs semanticaly but in reality it is a different approach

I must say I have a different take on the notion of negative punishments. To begin with I don't call them that and think the semantics of them is a problem because of the attitude it creates. I do not want to take anything away from the dog as a punishment so that they will decrease the chance of the behavior happening. I Reward the dog. Just not with the Reward they would prefer...
If my attitude remains that I am having a great time and even better if I am acting like I think that the Undesired Reward is what the dog wants I am not setting up a conflict. But I am motivating the dog to reexamine its choices. I am encouraging the dog to try and educate me as to the best thing to do. And when the dog figures out that biting and nipping me is the stupidest way to get me to play they will look for a better way. And when they think that the reward I offer is not worth the effort it weakens the probability of that behavior continuing to be offered.
If a good friend wants to get you to go golfing every weekend and you hate golf you could tell them how boring it is and keep debating the point forever.
Or you could enthusiastically head to the course wearing the most outrageous outfit you can put together at Goodwill. Hit the ball in the opposite direction because it is so much fun watching everyone's expression (besides you were never much of a conformist) Talk constantly. Hug them and scream with joy at every stroke they make and express your amazement at their skills. Then tell them what a wonderful time you have golfing with them and can't wait to do it again. I bet your friend won't be available for another round for months.
