Closer to a business or enterprise. To me it sounds like your Internet connection is sub-par. That is you should get a second connection or a much better one.
As to "does not select the fastest connection" that would be a question to the device maker. Same for the DHCP question. It's unlikely anyone owns that product.
Dear Huawei Community in CNET,
I hope you can point me in the right direction about an issue I have with my network.
I have an old house, plus 2 holiday cottages, all with thick walls. Based in Cornwall UK. The LAN comprises an E5186s-22a LTE gateway that works in conjunction with 4 hardwired edimax APs The wireless component is open and there are two SSIDS; one on channel 1 and 1 on channel 13. When the E5186s-22a is configured in Network settings Network = Auto and Network Search = Auto the LAN has good stability and great internet speeds often >30Mbs. I use an external aerial with good - excellent signal. Often with upto 20 devices connected. However during the summer holiday season the 4G network provided by my Carrier EE has problems with contention and speeds are low <1Mbs.
The action taken:
So I manually downshift to 3G on the E5186s-22a (Network settings = 3G only) and my wired win10PC has good internet speeds 10-15 Mbs and low contention.
When the the E5186s-22a is in 3G (Network settings = 3G only) wireless devices connected by directly to the Gateway or via the Edimax APs (hard-wired to the gateway) acquire a lease from the E5186s-22a but after a very short period (less than the 24hr lease) report no internet connection, even though wired devices such as my Win10 PC has internet access at all times. As soon as I upshift the E5186s-22a back to 4G the LAN connectivity issue to the internet is solved but I am stuck with a slow WAN due to 4G contention issues. When the E5186s-22a is in Auto (Network settings = Auto) it appears that it does not select the fastest connection, only the most modern Network I.e 4G - which as explained is not always the fastest. The LAN would be the perfect solution for our internet requirements if it were not for this issue.
I have a little network knowledge, but not enough to fully fault find this issue. What confuses me is why it only affects wireless devices (Windows, Android and Apple ) both directly connected to the E5186s-22a wireless and via the edimax APs wireless. I imagined TCP/IP packets and DHCP leases from the APs would be treated as a wired connection.
Does the E5186s-22a have known DHCP issues in 3G mode, or can you advise on a workaround?
Best regards, Rupert
