I went overdrawn at my bank, to buy this top of the range Fritz 7390 router. I already had, the eairler Fritz 7140 VOIP router, and was delighted with that, so, this new all singing all dancing router seemed just the job.
Well, it arrived, I was all excited, a new toy! However, when set up (it does this automatically if your ISP supports it, mine did) but, the download speed was appauling, I was previously getting around 6.6Mbs, with this 'new' router, harldy 1Mbs, terrible. I did factory reset, checked every detail, still only around 1Mbs, same even after a full manual setup.
So, I rang AVM Fritz at their Netherlands office, spoke to a guy, oh he said, try this new 'lab' firmware, and, give me a link in an email, I updated the firmware in the router to this new 'lab' version firmware, still the same, very poor down and up speeds, how frustrating!
My next telephone call was to the AVM Fritz Germany head office number, the same guy was on the phone as the Netherlands number Hmmmm!! At this point, he was extremely unhelpful, not wanting to discuss this, but, wanting me to detail events in emails, with screen shots, no doubt wanting to start a long and probably non productive string of emails, probably lasting months and, getting nowhere in the end.
I interupted him, saying, this was a brand new device, advertised as suitable for all international ISPs with Annex A or Annex B, regardless, so, it wasn't fit for the purpose, he give me the opinion, he didn't really care, needless to say, I was annoyed, as this attitude has been pointed out by other people contacting AVM Fritz technical support over router modem matters.
I use O2 as my ISP, it's ADSL2+ Annex A, which this Fritz box 7390 is supposed to support, if you are with O2, ADSL2+ like me, you will probably experience poor speeds too, if another ISP, you might be lucky and it work OK?
Amazon have been so helpful in this matter, they even sent another new router out, in case the first one was faulty, that's trust, I like that. The situtaion is now, I had to return it for a refund, a real shame, I would really have liked to have kept this router, it has tons of features I could use, but, alas, after sales from AVM Fritz, was extremely poor, in fact terrible, I tend to judge a company, on how good they are if you experience a problem with their equipment, AVM scored extremely low on this occasion.
