That sounds like an ajax issue to me, not related to 1and1 hosting.
I have successfully intalled WPMu and BuddPress using subdomains. My host is a local one here in Central Virginia and they have been very kind and helpful.

Well, I’ll chime in here. I prefer Slicehost.
It’s not for everyone. In fact, it’s not for most people. It is for us techie guys that want to control absolutely everything. It’s a company built by software developers for software developers.
When you purchase a slice, you have to install (yourself) the server OS, the web server, database servers, mail client, web packages, your custom files, etcetera. You are in total control of the environment. You basically build your own production box from scratch–although you actually are in control of a virtual machine on one of their servers unless you buy all the slices on a give physical box.
Blah, blah, blahbity, blah…
If any of this scares you, then Slicehost is not for you.
TMDHosting account, I got an account and planning on using them for BP with refer to they blog.
They provide good support for me on my problems.
I’m a Media Temple fan – in my opinion it has some of the best control panel features available, and it’s GridServer(gs) is fantastic for a shared server. It is also very easy to upgrade from a (gs) to any of their higher hosting plans.
I’ve been using MT for about 4 or 5 years now and I’ve never had an issue. They are a little pricey, but I think you get what you pay for and more.

Well i was using 1and1 and wanted to see what i could find that was best for BP. So what i did was sign up for a (mt) GS account and a TMD basic reseller account. After about 2 weeks of playing with them both i closed the (mt) account. TMD really offers more for the price and they will install buddypress for you just by requesting it. Usually withen 15 min.

Dont get me wrong they do have a few problems. Thats to be expected with a fairly new hosting company. For $29 a month i get a reseller account with great options. They use cPanel which i prefer Plesk but cPanel is ok.
(mt) is a great company with a great name. However i got the feeling the time i was with them they are more of a hype company has you seem to pay for the name and no the options. Their admin panel is a work of art though.
@Erichamby-
I hope that TMD works well for you!
Incidentally, I noticed that their BuddyPress tutorial is out of date. They have not been keeping up with the changes in theme directories. Also, they state that:
As an addon to the official WordPress MU, BuddyPress is fully compatible with all the plugins and themes of WordPress and does not limit its functionality in any way
This is not true. There are several incorrect statements there. For instance, there are a number of steps that must be taken if you are using a custom WordPress theme with BuddyPress. I hope they’re good at tech support!
i suggest linux vps or linux dedicated server not hostings, Debian if possible,
if configured as it has to be, it’s the best way,
all housing companies are good (assuming that the hardware is good) to run bp 
I am with many sites on MediaTemple Grid and it is pretty good. However some applications really have an impact on your usage. For instance the chatbar scripts really have an high impact. When I started using them I had to pay $150 in overusage each month.
Now I moved to MediaTemple Virtual Server dedicated virtual base and I have endless problems. The main problem is with the “othersockbuf” which has a soft limit of 1.433.738 and a hard limit of 2.662.538. Each time it hits that border the server dies. Which is NOW multiple times a day that I have to reboot the virtual server.
I’ve looked around the web but I could not find a solution. I really have no clue. So maybe i have to to somewhere without this limit.
UPDATE: I have simply clicked “update server from BASE to RAGE” and it seems all my problems are over…. (I also changed the mysql.cnf, killed spamassasin, killed watchdog, killed dns server, smb, secure SMTP…)
A simple solution but it works grin (although it now costs me $100 a month to run a buddypress site).
I also ran: http://kb.mediatemple.net/questions/816/%28dv%29+3.5+Auto-Tuning+your+server (MT has some great amount of docs on performance tuning)
I wonder if there shouldn’t be a BP group that talks about BP hosting. One topic for each host or something. Would be interesting to compare.
@edelwater-
If you’re having bandwidth issues, make sure that you are doing everything you can to optimize your setup. Here are some useful suggestions: https://codex.buddypress.org/getting-started/improving-performance/
@techguy-
If someone wants to start a group, that would be fine.
Ok, now I’m worried. I’m one of a growing number (I suspect) of users who’ve been attracted to setting up a BP/WPMU site by ease of installation, customization etc. and because we’re comfortable using WP for blogging. I chose shared hosting with Hostgator, having checked with them that a) BP and WPMU were supported and b) it was easy to enable wildcards etc. (limit of my technical knowledge reached – playing with anything beyond a bit of FTP is beyond me).
But it appears – from what others say in this thread – all the unlimited bandwidth stuff may have misled me (I’m NOT saying Hostgator did) and that my new site (which may well quickly end up with several thousand users – though most will just have profiles with half a dozen photos and won’t create blogs) could grind to a halt very quickly. Urgh….now I don’t know what to do! It seems from reading this I’ve made a bad decision…
I’m sure there will be those reading this who sigh that I shouldn’t be messing with things I don’t understand and should stick to a Yahoo group, but the point is that Buddypress and WP are accessible and enabling: so, some advice about what I should do going forward would be helpful and welcome.
gtn,
They shared hosts get you with the “unlimited bandwidth” Unfortunately, they don’t tell you that the CPU and Memory is limited. Shared hosts will only take you so far with BP, but then you’ll have to grow into something larger. Although, that’s a good problem to have. I wonder if someone won’t start a company just helping people scale BP beyond a shared host solution.
Anyone else like my idea of a separate group? Seems like it would be valuable since it’s an important part of the BP decision process.
I think there should also be more info about this issue in the Requirements section of buddypress.org – I read them, and assumed that shared hosting would be ok, as there was no warning.
Ok, I created the Hosting Group: https://buddypress.org/community/groups/buddypress-hosting/ It could use everyone’s feedback on the hosts they use and how it’s working for their setup.
