I've been suffering the same problems with wifi that many have reported with the Huawei HG633 not-so-Super Router:
- Billions of wireless error packets
- Random disconnects
- Repeated dropouts
- Dodgy streaming
And so I thought I'd share what I've done which seems to have fixed the problem.
I bought one of these: http://amzn.to/1Tfz6By for just under £20, it's a nano router, and plugged it into the HG633 by ethernet cable. (Note: I went for the 300mbps one)
Then, I've set it up in "Access Point Mode", so that it is pumping out a new wifi network, and transmitting everything by cable into the HG633 (thus bypassing the HG633's wifi problems).
Having run for a day so far, I've had no dropouts or disconnects, streaming is working perfectly, and a total of zero - yes, ZERO!!! wireless packet errors.
Obviously, YMMV, but seems to be working for me, and well worth the £20 for the sake of my sanity.
