Hi all,
I am having the same issue and have been since I got this Telkom Mobile package (10GB + 10GB with Huaweii B593 LTE Router/Modem)
I have tried all port forwarding tricks, customizing settings in Origin and BF4, customizing my router settings and every other possible avenue. I even went to the Telkom Direct store to see if I needed an Unrestricted APN which worked on my Vodacom SIM but Telkom Mobile/8ta doesn't have any APN restrictions to start with.
This is the most frustrating issue I have, since it is only for BF4 and no other games. I can't connect to any servers that don't display a ping in Server Browser, and there are only a few servers displaying pings. Every time I reset my router, I can see about 12 servers' pings, but within 5 minutes I can only see 3 or less (and they're usually empty). Also, if I do manage to get into a game, every time a round ends, I get disconnected at the start of the next map and am unable to join again.
Telkom Rep, please assist as I see you have finally PM'd some users.
PS To all the people trolling about ADSL, this line has outperformed every ADSL line I've ever had before:
43mbps download / 8mbps upload on speedtest.net
30ms ping / 2ms Jitter / NO PACKET LOSS on pingtest.net
