Hello,
May I confirm what is the detailed network diagram that how are these two WR841N connected to the HUAWEI router? Are they both connected to the HUAWEI router with Ethernet cables or by wireless?
Please be aware that we don't suggest you connect the two WR841N wirelessly in a daisy chain, which may have unstable wireless issues or you may have a speed issue when connecting to the 2nd WR841N.
If you want to connect both WR840N to the HUAWEI router with Ethernet cables, you may reconfigure them into Access Point mode as below:

BTW, what is the model number of your HUAWEI router? Ensure the internet is working fine when you connect more than one device to it.
Good day.
