Time Capsule suddenly very slow

I am using my new 2TB Time Capsule as a NAS in my home LAN. As such I back up my TV recordings on the TC and typically have WLAN transfer speeds of ~3MB/s between connected devices, such as a digital satellite receiver, MacBook Pro, Windows PC, etc... Since yesterday w/o any intervention by me the transfer rate dropped to < 100kB/s, and no modifications of the TC config. could change that.
Another, and perhaps linked, issue is that from time to time, when making backups from my satellite receiver hard disk to the TC, the entire connection drops out of the LAN. The receiver has then no more access to the internet for several hours.
One more strange observation is that the TC's green light every now and then blinks amber exactly when turning on the neon lights in the room. Apparently the switch-on transients of the neon starters influence the TC.
The TC is connected to a Netgear router to access the internet and is set up to provide a WLAN (see attached screen shots).
Looks like a hardware problem to me, or is there a bug somewhere else.
I would very much appreciate your help.
Thanks and Cheers,

I assume you're using Time Machine with your Mac. What happens when you open up Time Machine - can you browse your backup at speed or does it seem to stop or take forever to load as you move around in it? If so, sounds more like the hard drive dying. Especially if the issue with even internet access only occurs during attempts at accessing the drive on the TC.

Even that ~3MB/s seems slow to me. I've gotten 10-11MB/s when I had an old Cat5 cable connected to one of my machines and 50-90MB once I changed it out for a CAT5e with files under about 7GB and about 20-25MB with files of 20GB and larger.

I have a similar setup with my router providing DHCP services and the TC in bridged mode. Mine is one of the first gen.
