Hello,
I’m currently having an issue with my World of Warcraft (and Battle.net client to an extent). I get semi-frequent disconnects from the battle.net client, and while in World of Warcraft, I get constant “Transfer Aborted: Instance Not Found” issues.
I have conducted a few tests:
-For starters, I completely deleted every WoW & Battle.net associated file from my desktop and reinstalled the game from scratch; but that didn’t solve the issue, which lead me to believe it was due to connection rather than corrupted files within my game itself.
-Next I tried connecting to a VPN, which… actually solved the issue. While connected via a VPN, I never had the error pop up, and loading screens were 10x faster. However I would like to be able to play without needing a VPN as it increases latency.
So afterwards I contacted my ISP, and the support person informed me that, he had similar issues with battle.net (not WoW per se) having disconnections, and suggested it may be because my ISP uses CGNAT while battle.net requires an IP4; the tech support guy said once he added a static IP4 on his internet, it solved his connection issues.
So my question is simple: does Battle.Net require a IP4 for steady connections, and doesn’t support CGNAT networks? Naturally I would like to know for certain before I add a static IP to my ISP contract as they charge extra for it, and it may have just been a sales pitch on his part to get me to buy additional services.
Thanks for reading and I look forward to your response <3
-Sthéno.
TL;DR – Does Battle.Net only support IP4 and not CGNAT?
You could write country, so we know if it is “the problematic route”
This is one of excuses of one of ISP in my country, they use only IPv6 for their 5G GSM to home connection, and they are like “you need to use our device otherwise some websites will not work, bla bla bla” for that device you pay 15€/month , they offer for 100€ one time payment to change your public IPv6 to IPv4, they don’t write if it is dynamic or static (probably dynamic…)
and if you use your own GSM device they give you -50% FUP… by the way I am pretty sure this is against Commission Directive 2008/63/EC , but noone did report them yet…
then other better ISP in my country offer LTE/5G with IPv6, and I am pretty sure I have IPv4 CGNAT, because they offer 5€ one time payment for dynamic public IPv4, or monthly for static public IPv4
I use this LTE/5G internet , I didn’t pay the 5€ one time pay, and I have no disconnect issues with WoW, I have overall 99.99% uptime over the +1year I use that GSM connection to my home
so maybe change your ISP, or ask them for dynamic public IPv4 , if you don’t host servers, you mostly don’t need static public IPv4
I don’t know what router you have, but Mikrotik did release pretty good router hAP ax S / E62iUGS-2axD5axT , that could help too
and about IPv4, only the biggest ISPs of country have a lot IPv4 addresses, so smaller ISP need to use CGNAT for IPv4
IPv6 are plenty and cheap, it is mostly software/hardware issue (they need to update their stuff)
both mentioned ISP are the “almost monopolistic” GSM ISPs in my country (they are not small ISP)
These are not directly related to each other.
IPv4 and IPv6 are the basic protocols Internet runs on. WoW supports both, though I think during SL there were some issues with IPv6 connectivity. CGNET (Carrier Grade NAT) is used for IPv4 when the ISP does not have enough IPv4 addresses for the customers.
I don’t (knowingly) have experienced IPv6 but for several months I had mobile 5G connection with CGNET without any issues.
